I am developing a tool called locationAlarm.
This tool is fingerfriendly and available in every resolution, running the .net framework with the SenseSDK 1.39.
It can run with GPS and Triangulation, and will be the most relieable locationAlarm program that has ever been programmed!
Right now, it can wake you in a given radius close to your destiantion and is avaiable in german and english. Future features will be, that it warns the user if GPS and Network Services are out of reception and if the battery level gets critical.
App is now for download @ http://forum.xda-developers.com/showthread.php?t=834341
If you don't want to beta test, you can still stay tuned, I will release this software soon in several languages!
If you want your language to be supported, please ask for it in this thread!
