Description:
GateCacher is a Windows Mobile application for geocaching. It was specifically developed with "caching-on-the-go" in mind. In other words, you can download cache information directly from the geocaching.com website, request caches nearby and if needed, import GPX files generated by geocaching.com, facilitating "caching on a route".
* Finding caches - near you, near GPS coordinates, by cache (GC) code
* Support for multiple waypoints per cache
* Paperless caching -saves (stripped version of) information webpage from geocaching.com, including description, hints, additional waypoints, statistics, the first five logs and a clue editor
* Navigation, by compass, radar or GoogleMaps
* Basic coordinate calculations
* Navigation integration with Garmin Mobile XT, Route 66 v7 and TomTom
* Automatic saving on exit, so all information is maintained
