To complicated

App is just to needy so far. Its not as automatic as one would think;
1. If phone is off, no go
2. It stops tracking and you or other person have to re-boot system
3. You have to call person to turn app back on or reboot system
4. If you family or friend are in trouble and they dont have app running youll never find them.
5. Required lots of monitoring.

This is what Ive seen so far.
