With GeoWatch its possible to track your friends activity on Geocaching.com.
Simply add your friends to the list and you always know when theyve found something!
Never miss, when theyve found a new Cache!
For errors, suggestions or criticism just write a ticket:

This is much more effective than a critical review and ensures that the app always gets better - with your help!
