Does what it says. I tested on a friend and 1st try he knew how to disarm it. Maybe on an update you have to press the "home" button twice, or the home button and a user selected letter to disarm it! This way itll keep on barking to help u locate it. 2nd problem I noticed was no barking if you have the mute on. It should over ride the mute button.
