Always working

Me and my brother have been using this on each other for as long as I can remember! Never had an issue with it! It works best with guided access on so when the alarm is activated your thief cant dig through your phone. Turning guided access is so simple. Go to settings>general> accessibility> guided access and then set your passcode and go back on the alarm system app, TRIPPLE click the home button and fix up what ever you would like! Thank you!
