The app was wonderful until I upgraded! Today the app shows my son skipping school and going 45 minutes away! I have had no problems with him and found it hard to believe... but the gps says it! I worried, called School, a cussed him ( well I just asked... but) He swore he was at school! It just causes lots of issues! How can we trust it if this happens? Canceling my premium! Its a great idea, but it has to work! Btw... he was at school!
