FAQ - Frequently Asked Questions

General

Getting started

I am new to Geocaching. How does all of this work?

Explaining all details of Geocaching would be a little to much here.
However there are some facts you need to know to start Geocaching with c:geo:

1. You need an account on a geocaching platform to use it in c:geo:
We are supporting geocaching.com, which is an international caching platform, and Opencaching platforms in several countries (e.g. opencaching.de and opencaching.pl).
Choose the platform you would like to use, go to the website and create an account (basic accounts are usually free of charge).
After you retrieved a username and password for one of the platforms, enter them in c:geo settings to allow c:geo to login to the server.

2. You have to learn about the different cache types, D/T-ratings, etc.
You might not be successful finding a cache by just selecting a random one in c:geo and navigating to it. There is a lot more which you need to know in order to pick a cache which is suitable for you.
Most of the mentioned platforms offer detailed tutorials about how Geocaching works. We strongly suggest, that you read through these tutorials to learn what you need to know to find your first cache and how to log it.
Especially you should be aware of the different types of caches (You will typically not find a mystery cache at the given coordinates) and the T-rating (a rating of 5 means, that you need to climb/swim/dive to get the cache).

3. Find a cache near you and try it:
Use the "Live Map" or the "Nearby" function of c:geo to see which caches are around you. Pick a cache (a traditional cache with a low D/T rating will be a good startin point) which you would like to find and go for it!

Once again:
You should make yourself familiar with the different types, terrain ratings, attributes, etc. before starting out to find a cache.

I managed to login, but how to continue?

If you start c:geo the first time, it will directly take you to the service settings.
If you entered your username and password there, all you have to do is pressing the back key on your device until you reach the c:geo main menu. On the next start c:geo will automatically take you there.

If you are at the main menu we hope most function are self explaining. Otherwise you might also find some hints in this FAQ.

I see caches in c:geo, but how to get them?

If you managed to see caches on the map or in the nearby list, select a cache and open its details.
Read the listing text and pay attention to the D/T-ratings and attributes to learn more about how to log this cache.
If you are good to go, press the menu key and select "Navigate".

You will have several options depending on your needs. Here is a brief description of the most important navigation methods:
- Compass:
It will constantly show you distance and direction to the cache.
- Radar (optional):
If you installed an app supporting radar functions this will open a radar screen.
It is similar to the compass, but the working mode is a little different. You will typically see the cache coordinates as a marker on the radar. If the marker reaches the center, you reached the cache coordinates.
- Navigation (Drive, Walk, Cycle):
This will start turn-by-turn navigation using Google Maps

When you reach the coordinates, remember that GPS has an accuracy of several meters/feet only (also depending on your phones GPS performance). So you might to look around your position as well to find the cache.

How can I change to imperial units ?

c:geo uses metric units by default but should be able to detect if you are using a local setting which defaults to imperial units and will adapt to it automatically.

A manual change can be done in c:geo settings (main screen, Press menu, Select settings, Select Appearance) and select "Use Imperial units".

The help app does not work on my device

The help app is not authored by the c:geo team but by an user.
We think he did a great job, but unfortunately the app will not work on Android versions 3.0 or above due to a system limitation.

If you are affected by this problem just deinstall the help app and you will be redirected to http://manual.cgeo.org once you click the ?-icon in c:geo.
This will take you to the online version of his manual.
Be aware, that it has not been updated for quite a long time, so it might not cover new/changed functions.

For the future we are planning to implement an own manual if time permits.

General

Why do the cache details miss new information ?

In order to minimize the network traffic c:geo downloads caches only once and stores them temporary or permanently (if you save them on your list).

So if you miss some information (e.g. newest logs are missing, description has changed,etc.) please refresh the stored cache by selecting "Refresh" on the cache detail page.

Why are all cache coords wrong by some meters/feet ?

In case you are not logged in, the geocaching website does not provide correct coordinates.
It seems you did not provide login data or the login data is not correct.

Please go to c:geo settings, enter username and password and login.

The dates in the logbook are wrong or not shown at all

Currently we support the following date formats:

yyyy-MM-dd
yyyy/MM/dd
MM/dd/yyyy
dd/MMM/yyyy
MMM/dd/yyyy
dd MMM yy

(dd = day, MM = month, yyyy/yy = year)
The format can be changed on the geocaching websites user preferences page.

Maybe you notice that one format is missing: dd/MM/yyyy
The reason for this is quite simple: Is 04/10/2011 the 4th of October or 10th of April? So we would have to guess which would lead to inconsistency. Since MM/dd/yyyy is the default at the geocaching website we are supporting this.

No problems have ever been reported with MM/dd/yyyy. If you have problems please change the date format to this on the website and refresh the caches showing wrong dates.

I am not able to post a log online

If the button for posting a log to the geocaching website is labeled with "Logging not possible", this means that c:geo has not enough data to send the log. Check if you have an internet connection and wait a moment until the required data has been loaded.

In case you can not establish an internet connection you can also select to just save the log on your device and send it later by reaccessing the log page.

You can also batch submit offline stored logs as a fieldnote to the geocaching website at a later point of time.

Why does c:geo not use Groundspeak's public API ?

Let us answer this once and for all in one place. But let's start with basics.

There is very simple reason why us and groundspeak can't sync. We are a FREE, opensource application, they are a corporation. We give our software for no money, they would like to make profit with a service. They don't like what we do, we don't like what they do. It's like fire & water, cat & dog, hell & heaven....

The initial idea of c:geo is to provide a free (and open-source) app for mobile geocaching for everybody.

What would change with the API?

- c:geo only for premium members
- no support for OpenCaching or other platforms than geocaching.com
- Groundspeak-advertisements

There are also problems with the development:
- Development would take 2-4 months to implement the API
- During this time there would be only access to a testing-server, no nightly-builds
- Devlopers are using the development-build for caching
- The API requires a private key for the app. But c:geo is open-source. There are a lot of independent developers, but only one would get the key - all other developers wouldn't be able to test what they do
- c:geo would be no longer open-source
- Only a few core-developers allowed
- Much slower development

The Groundspeak's "public" API would fix most of our current problems, however c:geo would then force users to pay money to a corporation. This is not the opensource spirit.
If Groundspeak says OK to our idea then c:geo might have an API some day...

How do I send a log to the developers ?

If the app is not working as it should you can send a log to the developers.

When c:geo crashes or does not work properly iit writes debug messages to an android log if this option is set in c:geo settings.
This log contains data of all app for a short period of time (from several seconds to several minutes). Collecting a log as fast as possible after the crash is essential for us.

Here is a description how to do it.

I forgot my username and/or password

c:geo is only using the login details you are using on the geocaching website.

You have to go to geocaching.com to reset your password.
After you successfully restored your password there, please go to c:geo settings and enter the new login data.

After using c:geo the website is in english although I selected another language before

c:geo is accessing the geocaching website as a normal internet browser.
In order to retrieve the information from the website it needs to have reliable information. Therefore it will change the language to english when logging in, because c:geo can not support all different languages.

Feel free to change the language on the website back to your desired language anytime while using it.

I am basic member. How can I filter out PM-only caches ?

You can filter out PM-only caches on lists and search results by setting a filter.
The filter can be found in "Menu"->"Filter"->"Status"->"All member access".

Why does c:geo show 'Unkown Location' on the main screen ?

The address information shown at the bottom of the main screen is an information we receive from the Google online database based on your position. Sometimes Google has no address information for your location or the service is not running. In this case 'Unknown Location' or even a wrong city is shown.

This does not have any impact to the c:geo functionality. As long as you have a GPS-fix everything will work normal. If you want you can also disable the address information in c:geo settings so your coordinates are shown on the main screen instead of the address information.

Can I hide a cache and publish it using c:geo ?

Publishing a new cache with c:geo is not possible and there are no plans to implement this function.

However you can still use c:geo to record waypoints to help you planning your cache hide. To do so simply use the 'All destination' function which offers a history of coordinates you entered.

In order to e.g. beta-test an unpublished cache you will not be able to access the cache online (because it is unpublished) but you can import the cache via GPX or add the cache waypoints manually to another cache already stored on your device.


'Login failed' is shown on the main screen

If you are really sure you provided the correct login credentials in c:geo settings and still the login fails for you, this might be caused by traffic manipulation of your network provider to prevent tethering.

Sometimes network providers insert messages into the HTML-traffic which prevents c:geo from logging in while on mobile network.
A clear indication for this problem is, that c:geo only works on your WiFi connection at home but not while on a mobile network.

In this case please go to the c:geo settings and enable "Identify as android browser".
Afterwards you might have to restart c:geo or your phone to be sure these settings take effect.

If the problem still persists, please contact us and provide a log.

I have seen a 'Radar' function on other devices. How can I use that ?

c:geo is providing a compass function as navigation utility. The "Radar" function works together with the third party app called "GPS Status & Toolbox" availbel on PlayStore.

Once you installed the app c:geo will offer "Radar" as a navigation option.

What is the meaning of the symbols on the right side of a list ?

If you look at a list of caches (a search result or your caches saved on your device) the right side contains some symbols, colors and numbers. Here is a brief explanation of their meaning:

Color:
The color represents the average GCVote rating for this cache, where green means good (>3,5 stars),brown means average rating (between 2,5 and 3,5) and red means a rather bad rating (<2,5 stars). If the color is grey the cache has not yet any votes.

Number:
The number in this field represents the amount favorite points from geocaching.com issued to that cache by the users.

Symbol:
This is a marker which is shown if the cache contains Trackables.

c:geo constantly crashes when opening a cache

We applied a lot of improvements to the internal cache database in the last updates of c:geo.
If you have a lot of caches which are stored offline since many versions I might happen in rare cases that something in the database gets corrupted.
This may lead to the problem that c:geo crashes each time you invoke the database (i.e. open a new cache, access a stored cache).

The easiest was to solve this is to deinstall and reinstall the app, or go to the Android device settings->Apps->c:geo ->Delete all data.

Attention:
Both of these actions will reset c:geo completely. After that all stored caches will be deleted and you also need to reenter your login data.

For the future we are working on a detection and automatic fixing of corrupted databases.

Does c:geo support different coordinate formats ?

c:geo supports showing and entering coordinates in the following formats:

1. Degrees and decimal minutes (MinDec)
Notation: DDDº MM,MMM'
Example: N 51º 20,382 E 007º 01,820

2. Degrees, decimal minutes and seconds (DMS)
Notation: DDDº MM' SS,SSS''
Example: N 51º 20' 22,920'' E 007º 01' 49,200''

3. Only degrees (DegDec)
Notation: DDD.DDDDDº
Example: 51,339700º 7,030333º

Format 1 is commonly used for Geocaching and thus also the default notation used in c:geo.
You can change to the other formats by short tap on the cache coordinate line in the cache detail screen.
While entering coordinates in c:geo (e.g. when creating a waypoint) you can select the desired format in the headline of the dialog according to the notation listed above.

The conversion from and to UTM notation is currently not supported by c:geo.
However in case you need to convert coordinates to UTM you can copy the cache coordinates by long tap on them in the cache detail screen to perform conversion in another app.

Where does c:geo store photos taken while logging?

Starting with release version 2013.04.03 you have the possibility to attach a picture with you geocache log.
If you select to take a new picture it will be saved to a directory which follows a system default.
On most devices it can be found in a directory "/sdcard/Picures/cgeo".

Is it possible to edit posted log entries with c:geo ?

No, this is not possible.
We are currently not planning to implement this.
Please use the website for this rare case.

The nearby search has only approximated distance

When downloading nearby caches and you are not premium member the geocaching website does not provide coordinates in searches but only an estimation of the distance to the caches and "directional images".

c:geo uses this distance estimation and the "directional images".
You can sort the caches by distance but be aware, that the distance shown is the one based on your location when you performed that search. It will not change if your position changes.

To get exact coordinates as a basic member the CAPTCHA must be written or you have to download the cache to your device.
You can enable the CAPTCHA in the c:geo settings if desired. After entering the CAPTCHA c:geo will have the coordinates and proper sorting by distance is possible.

If you are BM and can not sort by distance, please update to the latest version of c:geo.
If you are PM and you can not sort by distance, please check your login.

Searching for GPX files takes a long time

c:geo scans the whole SD-card if it cannot find gpx files in the predefined folder. If you have a lot of files and folders on your SD-card this scanning might take some time.

It is useful to put all of your PQs into a specific folder and set this as the default import directory for gpx imports in the c:geo settings. This folder will be scanned first which will speed up the process.

c:geo data is always stored in internal memory

There are two things we are storing on your device:
1. The geocache database containing basically the content of your lists
2. The additional data (e.g. images, maps) for all the stored caches (in the database)

The database itself is stored in an internal folder on your device (not accessible without root access). Typically this database will only have a size of some megabyte.
The additional data can be much larger as it contains the images contained in the cache description and (optionally) the images retrieved from logs and (optionally) static maps.

For the database you can choose in the c:geo settings whether it is stored internally or on the SD-card.
The additional data is stored on SD-card by default (in a folder called .cgeo).

Some users are complaining, that the additional data as well as the database (if external storage is selected) are still stored in the internal memory of their devices.
We always place the folder on the storage medium that the device tells us is the sdcard. And in fact, technically this is on some devices only a part of the internal memory which is mounted as a SD-card (It's like a SD-card fixed mounted in your device).

Unfortunately there is no standardized method to find the location of a real SD-card on your device. There are some workarounds but those might fail on some devices, thus we decided not to implement them for now.
Furthermore we assume, that on each generation of new devices the amount of internal SD-card memory will get higher and higher, which does no longer require c:geo to use the real SD-card (which would also slow down the access time by the way).

Is c:geo available for Blackberry ?

Yes, c:geo is available for Blackberry.
The source code has been ported to Blackberry-OS by another developer and published in the Blackberry World:
http://appworld.blackberry.com/webstore/content/28277410

Please note that the c:geo team can not offer support for the Blackberry version, but you should contact the author directly in case of device specific questions and problems.


Can I login using my facebook account ?

No.
The login via facebook is an option only on the geocaching website.
In order to login to geocaching.com via c:geo you need to enter the username and password dedicated to the website.

In case you currently only use Facebook to login to geocaching.com, you have to go to the "Forgot Password" page on the website to set up a regular password first.
After you got this password you can use it together with your username to log in with c:geo.

Can c:geo post to Facebook?

No, currently c:geo does only support Twitter as a social network.
As the development team has limited ressources and is focussing on new geocaching features we currently do not have plans to implement a facebook connection.

However if you are twitter user already and/or you are looking for a way to post your findings to facebook, please note that there is a possibility to link Twitter to Facebook.
Doing so all your tweets will also be posted on Facebook (including the c:geo tweets).

You can find more info on the Twitter support pages.

We are planning to include a possibility to personalite the tweet contens, but right now we are always posting a standard text ("I found...")



I am not able to install c:geo from PlayStore

That is probably a wrong setting in your PlayStore. It has a content filtering with a rating that has four different levels, where "All" is the level which can be shown to all users. c:geo however is not on that level, because Google requires apps with position tracking to be level "Low".

To be able to install the app, you must either choose "Low" (pre-teen) or set the option "Install all apps" (which looks exactly like the "All" level, but has a completely different meaning).

A second reason could be, that your device is either not supporting GPS and/or Google Maps.
If you want to install c:geo anyway you can do this directly from our webpage by downloading the apk file.

Devices running on Android <2.1 are not supported by c:geo.

Submitting a log with picture takes a long time

As current smartphones can produce high-res pictures with a size of several MB the upload of those can take some minutes (depending on the connection speed) if you do not select to scale them.

Please consider using the c:geo scaling function to scale down the resolution before submitting the log.

Can I upload a picture with my log ?

c:geo supports attaching pictures to your logs. You will find the attach button on the logging page directly below the submit button. After selecting it you can either attach a existing picture or take a new one.

Why does c:geo not work on my device ?

That is the most common question but there can be several reasons that c:geo is not working as it should.

You should do the following steps:
- First of all please check if you are using the latest version (check on PlayStore for updates or load the latest version from our website). If you are using an outdated version please update, because there might be changes on the geocaching website which need a new version of c:geo to work.

- Go to c:geo settings and check your login. If it fails please make sure you are using the correct login credentials. Those are the same you use for the geocaching website.

- Check our facebook page to see if others also have a problem and/or we reported a known problem there. In parallel you might also receive a notification on the c:geo main screen if there are known problems.

- c:geo is only supported for devices runnind Android 2.1 or above.

If your problem is still not solved, please contact us on Facebook or via email. We will answer as soon as possible.

The nearby search also retuns cache far away from my position

Besides geocaching.com c:geo is also supporting opencaching platforms for several countries. If you activate the opencaching service in the c:geo settings the nearby search will also provide you the nearest opencaching caches.

However if you accidentally activate an opencaching platform of a foreign country (e.g. you are living in the USA and have activated "opencaching.de") you will see caches some 1000 miles away in the nearby list.
In this case please deactivate the not needed opencaching platforms (via c:geo Settings -> Services -> Opencaching.xx).

My compass shows wrong directions or stops moving

In 99% of these cases the problem is your device. c:geo only uses the position- and compass-information provided by the Android system.

Please first of all try to calibrate the compass sensors of your device. On most devices this can be done by turning the devices around all of its axis three times or moving it horizontally in shape of the number 8 until the compass shows the right magnetic direction.
Please be aware that electric field (such as high voltage lines near to you) might influence the device sensors.

Please do also check if you activated the magnetic sensor. Pres the menu key while the compass is active. In this menu you can choose "Use GPS only" or "Use GPS and Magnetic compass". Be sure to use GPS and magnetic compass for maximum accuracy. (Note: If your device does not have a magnetic compass this option can not be set).

If the problem is still not solved you should try another app with compass functionality (e.g. "GPS Status & Toolbox) to verify your device capabilities.

Furthermore there is a known bug on some Samsung devices (e.g. Samsung Galaxy S2) where the distance gets stuck for some seconds as the device is always reporting the same position although it changes. This will hopefully be solved by Samsung soon.

If nothing helps and the problem persists, please contact us.

How can I change to imperial units ?

c:geo uses metric units by default but should be able to detect if you are using a local setting which defaults to imperial units and will adapt to it automatically.

A manual change can be done in c:geo settings (main screen, Press menu, Select settings, Select Appearance) and select "Use Imperial units".

Is c:geo available for iPhone or Windows Phone ?

No.
c:geo is written for Android and has more than 50 000 lines of code. We will not port it to iOS or other non-android systems because it is too much work. Furthermore the iOS AppStore / Apple is very restrictive and most of us don't like it.


But:
c:geo is open source! That means that you can get the code from GitHub and rewrite it for iOS. Feel free to port (and maintain) it, but please keep the open source license in mind.

I recently upgraded to a premium membership but I can't use PM functions in c:geo

While logging in c:geo will learn if you are basic or premium member, but c:geo will only perform a login if it is necessary.
So directly after you got a premium member it can happen, that c:geo does not know this yet.
In this case you can force c:geo to login by either entering the settings and select "Check Login" or simply reboot your phone.

Translations are missing in c:geo for my language

We recently started using a crowd-sourced translation platform to improve the translation and even include new languages.

If you see untranslated (i.e. english) prompts or your language is not even supported, you are invited to contribute on this platform!

Please have a look here:
Crowdin.net c:geo

After creating a free account you can start contributing translations or vote for existing proposals right away.

Logs made with c:geo are truncated on the website

Especially with geocaching.com it may happen that log texts are interpreted as HTML code although they are not written in HTML.

if you e.g. include a "<" or ">" sign in your log, it may appear truncated or bad formatted later. This does not only affect c:geo but also if you write this kind of log direclty on the website.

Reason for this is a bad implementation for HTML-detection on the website, but no fault in c:geo.
You need either to avoid such special characters in your log or use HTML-formatted logs to work around this problem.

My device does not have a menu key (e.g. HTC, Acer, Motorola, Samsung S5)

A soft- or hardkey for the menu (menu button, three-dot-button) should be somewhere on your device by default, which is used to open the menu while c:geo is running.

However some vendors implemented a slightly different solution on some devices:

To access the menu on HTC devices (e.g. model One V) you have to pres and hold the app-switch button. The app-switch button is the right most button with the two overlapping squares.

On some Acer devices (e.g. Acer Liquid Z3) you have to double tap the right softkey to open the menu.

On some Motorola devices (e.g. Android Mini) you have to either long press the "recent apps" button or enable the on screen menu key in your android system settings as follows: Settings -> Display -> Unselect "Use long press for menu". After this a three-dot softkey should be shown right above your hard keys on your screen.

On the new Samsung Galaxy S5 you need to long press the lower left (app-switch) button to open the menu.

Live map

What are these different markers for caches on live map ?

In order to provide more info about the status of a cache c:geo provides several markers which are shown together with the cache icon on the live map.

Below you will find a rough description of them:

- Personal Note available (Pen icon)
- Modified coordinates available (Flagpost icon)
- Caches is saved on device (Disk icon)
- Offline log is stored (Red smiley)
- Own cache (Star)
- Cache found (Smiley)

I do see ??-caches and orange circles on the live map

It is normal, that you will sometimes see ??-caches and caches with orange circles on the live map.

The ??-caches mean, that c:geo was not able to identify the type of this cache.
This mostly happens if too many caches are displayed at once (i.e. your zoom level is very low or the cache densitiy is very high).
If you reduce the amount of caches shown (by zooming in) or if you click on a specific cache you will get the info about the cache type.

The caches with orange circles mean, that c:geo does only have a graphical approximation of the cache coordinates. The accuracy of the cache position on the map depends on the zoom level and maybe some meters/feet off. The closer you zoom in the more precise the cache position will get.
To retrieve precise coordinates for the map you can also open the cache details once or store the cache for offline. In these cases the orange circle will disappear indicating that the coordinates are precise.

You can influence the accuracy and completeness of the live map by selecting an appropriate live map loading strategy as described in What is the difference in Live map strategies




What is the difference between the live map strategies ?

Depending on your requirements the live map offers four different strategies.
Some are focused on fast loading, some on accuracy of cache positions and information.

You can select the strategy while on live map in "Menu"->"Strategy"
This is the meaning of the different options:

- Fastest: Load approximated cache coordinates only and don't identify the cache type
- Fast: Same as fastest but try to identify the cache type
- Detailed: Same as fast but load details for 20 caches around your position
- Speed dependent: Automatic switch from "Detailed" to "Fast" at 30km/h (This is the default)

For getting most accurate information you should select "Detailed", for a fast loading and less priority on detailed information you should select "Fastest" or "Fast".

The "fast" strategy will only identify "Traditional", "Multi", "Mystery" and "Event" caches. Other cache types will be shown as ??-caches.

The live map is still showing own/found caches although I selected not to show them

This is the same as in the live map on the geocaching website.
If you zoom out to a huge area own/found caches will no longer be hidden.

Please zoom in to allow c:geo to detect own/found and hide them out.

Starting Live Map freezes or crashes c:geo

If c:geo freezes or crashes when starting the (live) map please send us a log (refer to "How to send a log").

To get around this problem start c:geo, go to the settings and change the map to OSM.
Now start live map, it should work. After live map is started you can switch back to Google if desired.

Is there an easy way to open the live map for a distant location ?

Yes, there is an easy way to do this without the need to zoom/scroll around:
Perform a search for the desired address/region. Once the results are displayed, click on the map icon in the upper right.
You will get the map for the location already containing the caches from your search. You can now use "Menu"->"Enable live" to activate the live map function.

The live map is not showing any cache

Please make sure that live mode is enabled. You might have accidentally disabled it.
Live Map -> Menu -> Enable live

You can see whether live is enabled or not by looking at the headline:
"Map" means live mode is disabled
"Live Map" means live mode is enabled

send2cgeo

What and where is send2cgeo ?

Send to c:geo is a quicker way to transfer a cache opened in your browser to c:geo.
You will find an overview and description of it here: http://send2.cgeo.org

How do I register for send2cgeo ?

To use send2cgeo you need to:
a) register your browser to our servers
b) register your device to our servers
c) connect your device to your server.

Registering your browser is easy. Open the send2cgeo page and click Register in your browser. After registration you can add "a friendly name".

Registering your device is done in the c:geo settings. You can set a name and click "Register". After registration you will get a PIN number. The PIN is valid only once and only for about an hour. You can always request new PIN.

After you have both things registered open a send2cgeo page in browser, click "Add device", enter your PIN given by android phone and click add.

That's all !

How to transfer caches with send2cgeo ?

In c:geo open the list of stored caches where you want to import the caches to and select "Menu"->"Manage"->"Import from web". After that c:geo waits for new caches from send2cgeo.

In your browser open a cache on the geocaching website and if the send2cgeo script is installed and activated you should have a button or link "send to c:geo" on some pages.
After you selected it the cache information will be transferred to your device and stored in the list.

Currently we support the following pages:
- Cache details page ("Send to c:geo" button right next to "Send to my phone")
- Geocaching Live Map ("Send to c:geo" link in the popup for a cache)
- Search Results page (Small phone icon in the most right column of the list)
- Recently Viewed Caches page (Small phone icon in the most right column of the list)

How do I install send2cgeo with Google Chrome browser ?

Since some versions Chrome does no longer allow installation of user-scripts except if they are provided via the Chrome Webstore.

However there is a workaround for it:
1. Download the send2cgeo script and save it on your local drive.
2. Open Chrome and go to Chrome settings page (Menu icon->Settings).
3. Select the tab "Extensions" and leave it open.
4. Now open a Windows Explorer and simply drag and drop the send2cgeo script (the file you previously saved to your local drive) to the extensions page.
5. You should now see that the send2cgeo script is installed and active
6. Now proceed with registration of browser and device as written in our description



I tried to register my device but it shows 'Registation failed'

Registering a device is only needed for send2cgeo.

If it fails the reason can be one of the following:
a) Your device does not have internet connection
b) Our servers are down or busy
c) A communication error or timeout occurred

You can try again in couple of minutes (or hours) and if it persists contact our support.

The option 'Import from web' is no longer shown

In this case your device got unregistered from the send2cgeo website due to inactivity or you reinstalled c:geo on your device.

Please re-register your device and it will work again.

Can I use multiple browsers and/or devices ?

Yes, multiple devices can be on multiple browsers.

You need to "Register the device" for every browser. The PIN can only be used once.

On the website "Register first" is shown but I am registered

OpenStreetMap

What is OSM:Offline ?

OSM:Offline offers you the possibility to use all the map functionality of c:geo even when your device is not connected to the internet. This can be useful e.g. in case of roaming to avoid expensive data transfer or when you are in regions without or with slow network connection.

In combination with caches already stored in c:geo (manually or via GPX import) and the possibility for offline-logging (e.g. for later fieldnote export) you will get a full offline solution for caching.

How to use an OSM:Offline map ?

Once you downloaded or created a map, store it into a folder (e.g. /mfmaps) on your device or SD-card. You can also store mulitple maps (e.g. for several countries) into this folder to have easy access later directly from c:geo.
If you are additionally using Locus it is useful to store the maps in /Locus/mapsVector to have them accessible for Locus as well as for c:geo.

Afterwards go to the c:geo settings page in the section "Map Sources" and either enter the directory where the maps are located manually or simply press the "..." button to start a scan for map files and select one of them.

In order for c:geo to use the selected map you have to activate OSM:Offline in the dropdown menu located above the directory settings. You can change this setting also directly from live map.

If you now access any map functionality (live map, cache map,etc.) the offline file will be used.
You can quickly switch between different offline maps or switch back to online maps using "Menu"->"Map view" while in a map.

How to use custom themes for OSM:Offline ?

c:geo is supporting custom rendering themes for OSM:Offline maps. These can be used to change the color style of the map (e.g. to have a nightview map) or to highlight certain objects within the map (e.g. cycle paths or height lines).

Up to now we do not have build-in themes but you need to create them by yourself or download some user-made themes from the internet. Try e.g. searching for "RGB Night Theme for Vectormaps" to find appropriate nightview-themes. Build-in themes in c:geo might come in one of the next versions.

If you have created a personal version of a theme which you are willing to share with us, feel free to contact us.

After having downloaded a theme-pacakge (usually a ZIP-file containing a lot of xml files and graphics) exract it including all its sub-directories into a folder in your device or SD-card. Afterwards select this folder as base-folder for map themes in c:geo settings.

If you have done it right and the theme is valid it should now be selectable from live map via "Menu"->"Map modes"->"Select map theme".

Are there known problems for OSM:Offline ?

Yes, the mapsforge library has several problems which we know of:

- If you try to start several instances of maps recursively (e.g. Live map -> Open cache -> Navigate -> Map) this may lead to memory problems depending on your device which can end up in a crash. Try to avoid using several map instances.

- Large map files can cause a really slow rendering and sometimes even a crash. Try smaller files in these cases.

- In older versions of c:geo map files in version 0.3.0 have been rendered very slow on some devices. We applied a workaround for this and hope, that this is solved. If you experience such a problem, please contact us.

Where to get an OSM:Offline map ?

c:geo supports offline maps from mapsforge in versions 0.3.0 and 0.2.4. Using v0.3.0 maps is recommended as the support for v0.2.4 might be discontinued in a future version of c:geo.

Many OSM:Offline maps are already pre-made on the mapsforge website. Almost all countries are there to download and will be updated frequently.
If you would like to create your own map please read this instructions.

Users made us aware that Openandromaps also offers free, compatible offline maps for many countries and regions. These maps are even including some custom map themes suitable for hiking or cycling (including the display of height lines/isohypses).

Offline caching

Can I use c:geo also for offline caching ?

The main purpose of c:geo is to have an online access to your geocaching platform.
However c:geo also provides an offline functionality to use it without any network connection (e.g. while caching abroad).

In order to use c:geo completely offline you will have to prepare some things depending on your needs:
1. Store the caches for offline use (manually or via GPX import).
2. Optionally download an offline map as described in OpenStreetMap

In case you want to avoid any data transfer you should generally disable the internet connection on your device anyhow, because c:geo will always try to login once you started it.
On most devices the internet connection is disconnected automatically in roaming conditions or if the mobile part is switched off.

To allow offline logging of caches please go to c:geo settings and check "Enable offline logging".
After checking this c:geo will not post logs online but only to store the found status offline.
Afterwards you can either upload the logs via field note export or reaccess the log page and submit online while having an internet connection.

What are fieldnotes and how do I use them ?

Fieldnotes are supported by the geocaching website to allow an offline logging of cache finds and batch uploading them to the website.
c:geo is supporting fieldnote export and also automatic uploading to the website.

If you save your cache logs offline only in c:geo (e.g. when caching abroad) you have the possibility to export these logs as fieldnote instead of logging them online.
The offline logged caches are marked by an orange line in your lists. To export the logs you have to select "Menu"->"Manage"->"Export"->"Fieldnotes".
From there you can either only export the fieldnote file to your device or export them and additionally upload them to the geocaching website.

After you exported your fieldnotes to the geocaching website, the website will show that you have pending fieldnotes and you can compose your logs in your browser.
Please be aware that it might take some minutes until the website alerts you of having pending fieldnotes.


How to use an OSM:Offline map ?

Once you downloaded or created a map, store it into a folder (e.g. /mfmaps) on your device or SD-card. You can also store mulitple maps (e.g. for several countries) into this folder to have easy access later directly from c:geo.

If you now access any map functionality (live map, cache map,etc.) the offline file will be used.
You can quickly switch between different offline maps or switch back to online maps using "Menu"->"Map view" while in a map.

What are static maps ?

c:geo optionally downloads google maps snapshots of the area around the cache and its waypoints for offline usage while storing a cache.
It will download satellite views as well as map views on different zoom levels. So you will have a map function also in case you don't have an internet connection and you don't use an OSM:Offline map.

You can enable the function in c:geo settings for the cache position and for additional waypoints.
To access the static maps please select "Menu"->"Navigate"->"Static Maps" from cache details.


Why do some caches not have a static map ?

Google limits the download of static maps to 1000 requests per day.
So if you batch download/refresh a lot of caches this limit can be reached easily (because for each cache at least five maps are loaded and optionally even more if you enabled the download also for waypoints of a cache).

If the limit is reached you will have to wait for the next day to get more static maps. c:geo will automatically refresh those caches without a static map first.

How to use field notes with c:geo ?

c:geo is supporting the export of field notes and (optionally) the automatic upload of these field notes to the geocaching.com website.

To use them you just have to compose your logs in c:geo and save it in the section 'Offline Log' instead of submitting them online. If you (optionally) add a log text, this text will also be exported with the field-notes. You can also compose logs of types other than 'Found'.

After you finished caching go to your list and select 'Menu'->'Manage'->'Export'->'Field Notes'.
You can select to only export them to your device or also upload them directly to the website (of course you need an internet connection to upload the field notes).

The option 'Since last export' will check the last upload on geocaching.com and only export those not already uploaded to the website.

Please notice:
The logs uploaded to the website will not be automatically published but be available for review and submitting once you access the website. That is how it generally works on geocaching.com.
There will be a notification on the website telling you that you have pending field notes and will take you to a page where you can submit the logs and also edit before submitting.

Is it possible to batch submit offline logs in c:geo ?

This is not (yet) possible.
We are thinking about implementing this but we encourage you to use the existing field note submission for the time being (see other FAQ-entries).

Opencaching platforms

The nearby search also retuns cache far away from my position

Besides geocaching.com c:geo is also supporting opencaching platforms for several countries. If you activate the opencaching service in the c:geo settings the nearby search will also provide you the nearest opencaching caches.

However if you accidentally activate an opencaching platform of a foreign country (e.g. you are living in the USA and have activated "opencaching.de") you will see caches some 1000 miles away in the nearby list.
In this case please deactivate the not needed opencaching platforms (via c:geo Settings -> Services -> Opencaching.xx).

Can I log an opencaching cache within c:geo ?

Starting with version 2013.08.24 we support online logging for opencaching.de and opencaching.pl.
Support for more platforms will come with later versions.

Do you support Geokretys ?

Starting with version 2013.08.24 c:geo has a basic support for Geokretys.
You can use the trackable search function and look up a Geokrety code to get information about the trackable. Online logging of Geokretys is not yet supported.

Will there ever be more functions for opencaching ?

Yes, definitely.
Right now we implemented the OKAPI interface which allows access to opencaching platforms in several countries. We will add the support of new countries supporting this interface with the next versions.


Is c:geo also supporting opencaching ?

There is already a basic support of opencaching platforms in c:geo.

1. Starting with version 2013.08.24 we support the OKAPI-interface for the following opencaching platforms:
- Opencaching Germany (DE)
- Opencaching Poland (NL)
You have to activate the platform and authorize yourself within the c:geo settings.
Afterwards opencaching caches will be shown on live map, nearby search and you can post logs online.

2. You can search for a OC-code with the search function. This will work with all opencaching platforms supporting the OC-API or OKAPI, which are currently:
- Opencaching USA (OU)
- Opencaching Poland (OP)
- Opencaching UK (OK)
- Opencaching Netherlands (OL)
- Opencaching Germany (DE)

3. You can import GPX files from opencaching platforms to store the caches in your lists within c:geo.


Opencaching caches you have stored in your lists will be shown on the live map in parallel to geocaching.com caches.


The authorisation always fails or does not start

Some users report that either the authorization procedure does not start at all or always fails.

If this is happening to you, please check that your device has the correct date, time and timezone information. For security reasons the Opencaching API will reject requests which are not matching the server time (+- 5 minutes).

Device specific

Searching for GPX files takes a long time

c:geo scans the whole SD-card if it cannot find gpx files in the predefined folder. If you have a lot of files and folders on your SD-card this scanning might take some time.

It is useful to put all of your PQs into a specific folder and set this as the default import directory for gpx imports in the c:geo settings. This folder will be scanned first which will speed up the process.

The distance to a cache is fluctuating heavily

For some users the distance to a cache in a list of caches or in the compass is jumping between some meters to some kilometers.

You are probably running Cyanogenmod ROM. This is a known bug in Cyanogenmod 10.
More information can be found here:
http://code.google.com/p/cyanogenmod/issues/detail?id=6883

So you either have to wait for a fix for this ROM or change to another ROM.

c:geo data is always stored in internal memory

There are two things we are storing on your device:
1. The geocache database containing basically the content of your lists
2. The additional data (e.g. images, maps) for all the stored caches (in the database)

The database itself is stored in an internal folder on your device (not accessible without root access). Typically this database will only have a size of some megabyte.
The additional data can be much larger as it contains the images contained in the cache description and (optionally) the images retrieved from logs and (optionally) static maps.

For the database you can choose in the c:geo settings whether it is stored internally or on the SD-card.
The additional data is stored on SD-card by default (in a folder called .cgeo).

Some users are complaining, that the additional data as well as the database (if external storage is selected) are still stored in the internal memory of their devices.
We always place the folder on the storage medium that the device tells us is the sdcard. And in fact, technically this is on some devices only a part of the internal memory which is mounted as a SD-card (It's like a SD-card fixed mounted in your device).

Unfortunately there is no standardized method to find the location of a real SD-card on your device. There are some workarounds but those might fail on some devices, thus we decided not to implement them for now.
Furthermore we assume, that on each generation of new devices the amount of internal SD-card memory will get higher and higher, which does no longer require c:geo to use the real SD-card (which would also slow down the access time by the way).

Why does c:geo not work on my device ?

That is the most common question but there can be several reasons that c:geo is not working as it should.

You should do the following steps:
- First of all please check if you are using the latest version (check on PlayStore for updates or load the latest version from our website). If you are using an outdated version please update, because there might be changes on the geocaching website which need a new version of c:geo to work.

- Go to c:geo settings and check your login. If it fails please make sure you are using the correct login credentials. Those are the same you use for the geocaching website.

- Check our facebook page to see if others also have a problem and/or we reported a known problem there. In parallel you might also receive a notification on the c:geo main screen if there are known problems.

- c:geo is only supported for devices runnind Android 2.1 or above.

If your problem is still not solved, please contact us on Facebook or via email. We will answer as soon as possible.

My compass shows wrong directions or stops moving

In 99% of these cases the problem is your device. c:geo only uses the position- and compass-information provided by the Android system.

Please first of all try to calibrate the compass sensors of your device. On most devices this can be done by turning the devices around all of its axis three times or moving it horizontally in shape of the number 8 until the compass shows the right magnetic direction.
Please be aware that electric field (such as high voltage lines near to you) might influence the device sensors.

Please do also check if you activated the magnetic sensor. Pres the menu key while the compass is active. In this menu you can choose "Use GPS only" or "Use GPS and Magnetic compass". Be sure to use GPS and magnetic compass for maximum accuracy. (Note: If your device does not have a magnetic compass this option can not be set).

If the problem is still not solved you should try another app with compass functionality (e.g. "GPS Status & Toolbox) to verify your device capabilities.

Furthermore there is a known bug on some Samsung devices (e.g. Samsung Galaxy S2) where the distance gets stuck for some seconds as the device is always reporting the same position although it changes. This will hopefully be solved by Samsung soon.

If nothing helps and the problem persists, please contact us.

The help app does not work on my device

The help app is not authored by the c:geo team but by an user.
We think he did a great job, but unfortunately the app will not work on Android versions 3.0 or above due to a system limitation.

If you are affected by this problem just deinstall the help app and you will be redirected to http://manual.cgeo.org once you click the ?-icon in c:geo.
This will take you to the online version of his manual.
Be aware, that it has not been updated for quite a long time, so it might not cover new/changed functions.

For the future we are planning to implement an own manual if time permits.

The new c:geo version is shown as incompatible

We decided to drop the support of Android versions below 2.3.
Only a very minor percentage of our users are affected.

The reason for this is, that we want to include more features and further improve usability and stability.
Newer Android versions offer a lot more possibilities which we simply can not use if we have to be compatible to e.g. Android 1.6.

Please check if the manufacturer offers an update for your device. If there is no official update it may also be possible to use a Custom-ROM (like Cyanogenmod) if it is available for your device.
If nothing can be done to update your device you should consider using a new(er) device running on an Android version 2.3 or above.

Additionally we offer a legacy version of c:geo, which is compatible for devices with Android versions 2.1 and 2.2 for the time being. This version will not be updated with new features anymore, critical bugfixes might be done if considered necessary.

The PlayStore will automatically offer the matching version for you to download and install.

c:geo contacts plugin

The contact is not matched although it is stored

Please make sure you stored the geocaching name of the person like it is shown in c:geo in the "alias" field of the contact in your phonebook.
Alternatively the plugin will also match if the geocaching name equals the full name stored in your phonebook.
