If a new version is considered to be ready to be released (a so called “Release candidate”), we might in a first step make it available as beta version to get user feedback and be able to find bugs or problems we did not yet see during the development.

The beta versions are also distributed over Google Play and work seamlessly together with updating from and to our release versions automatically. All you need to do is enable beta testing for c:geo on Google Play by following this link:

Become beta tester for c:geo!

After you activated the beta testing, you will receive beta versions alongside with the official versions via Google Play. This means, that you will still receive all official versions but also additionally receive an update if a newer beta version is available. Furthermore you can as a beta tester send us your feedback and problem reports via a dedicated Google Play feedback form.

While you are subscribed to the beta testing Google Play (for some reason) always shows c:geo(Beta) in the store entry, also while we currently might not even have an active beta version but you are on the official release version. If you look into About c:geo you can check if you are currently using a beta version: If there is a suffix -RC in the version number, it is a beta version.

If you wish to discontinue beta testing just use the link above and deselect the beta testing mode. Afterwards you might need to uninstall the beta version from your device and reinstall the normal version from Google Play.
