Geocaching is an outdoor treasure-hunting game in which the participants use a Global Positioning System (GPS) receiver or other navigational techniques to hide and seek containers (called "geocaches" or "caches") anywhere in the world. A typical cache is a small waterproof container containing a logbook and "treasure," usually toys or trinkets of little value. (from http://www.wikipedia.org)
An application for geocaching guides you to a cache with direction and distance, of course. But it should also be possible to download additional information like description, logs and hints for a cache.
- Distance and direction to a cache
- Additional information of the cache
- Alert me, if I'm (unintentional) nearby a cache
- Support for Wherigo cartridges (However, it seems that the file format isn't open.)
