In order to use c:geo, you need an account of a geocaching platform of your choice. Without such an account for a geocaching platform c:geo will not show any caches!
c:geo currently supports geocaching.com, an international commercial geocaching platform, as well as Opencaching platforms in several countries(e.g. Opencaching USA, Opencaching UK, and many more). Select a platform you would like to use, and upfront create an user account on their web page (Basic accounts are normally free of charge).
If the registration fails, please take a look in our FAQ to get help.
You can find more information regarding the geocaching services supported by c:geo here.
If you receive an error message or you do not return to c:geo, please try to use another browser for registration. Please also check, if date and time on your device are correctly set.
