It doesnt track anyone

This stupid app doesnt work.My son was at his friends house for 3 hours. I kept checking his location to make sure they are not sneaking out to 7Elven to buy junk. It showing that he was home even though I was texting him back and forth and his friend lives across town. Dont bother
