Could be #1 Power-App - if it would work.

Thoroughly tested this App, using iPhone 3GS (iOS 6.1.1) and 2 iPhone 5 (iOS 7.0.4).
Started working well with tracking my daughters iPhone 3GS, then started just randomly setting waypoints, then partly none for about 2 weeks. Then again started setting waypoints, but far too late.
Using iPhone 5 is unreliable. Only 1-2 waypoints daily max., randomly set. Exhausted all possible settings and combinations.
2 Stars for the idea and the possibilities one could have - if it would work.
Much work to do though.
I definately wont buy a subscription for a non-reliable app. My test period ends tomorrow, and Ill probably delete it.
Could be THE Power App, if it would work reliable.
Let me know ig it does, and Ill be back.
