Sentry Bot will help you to protect your phone or room by detecting movement or sound once armed. Select 1 of 7 different and loud alarms to startle anyone who tries to pickup your phone or enters your room. We recommend hooking your phone up to your speakers when protecting your room for added effect! NOTE: The accelerometer is not intended to work during lock screen with the Windows Phone OS. Although it can work in lock screen, if it stops working we recommend you reboot the phone. We also recommend you use sound detection if you intend to lock the screen. Don't forget to set a password for your lock screen in Settings->lock+wallpaper!
