Unlike description autolock is not disabled with this app. A siren sounds every few seconds even when phone is asleep and on my desk and main alarm will not go off until I enter my phones autolock passcode no matter how many times i pick up the phone. Sort of defeats the purpose of having a burglar alarm if it doesnt go off until I unlock the phone.
