Fantastic alarm function working in the background will let you know when you are reaching within a set distance of your destination point.
Notice: the alarm function works in the background just using cell tower triangulation so,
it only works with iPhone and iPad 3G .
The accuracy will depend on how many cell towers are within reach.
Expect lower accuracy when outside city limits.
It only gets refreshed when position changes significantly.
It does not impact significantly on your device battery life.
Disclaimer:Continued use of GPS running in the background can dramatically decrease battery life.
