Just like you do with a home security alarm for your house, you can set up this app, arm it, and trust it to go off loudly if anyone tries to touch your phone while you’re not around. Unlike those home security devices, the Burglar Alarm App is completely free to use. It’s a handy app for parties, crowded public areas, or if you are a politician who has a tendency to send inappropriate images of yourself to woman around the internet. It even works even when the lock screen is on. With this app, hopefully you’ll be one step closer to never having to be that person who creates the ‘Lost/stolen phone, need numbers” event on Facebook.
