This is a great idea for poor people living on the margins of society who can't afford an alarm system or don't have a strong lock.

Are you sure this hasn't been done already? what's your top 5 competitors. Also, can you make my phone also work like a bicycle turn indicator when I strap it on the back of my bicycle helmet and have the ear piece in, it should let me say "turn left" and then show a turn left signal for the cars behind me. oh, and is there an app that lets me use my cell phone like a body camera? like maybe you can combine that with the turn signal bicycle helmet light app so it's always recording the cars behind me on like a 5 minute or 15 minute loop so if I get hit I can record the video from before the accident. maybe the phone should flash the words "you are on video camera" one word at a time when it's on the back of my bicycle at an intersection when I'm stopped to reassure the driver behind me I care about safety. I'm in San francisco and the app you created makes sense to me. but my concern is update and installation hassle since I really don't use that sort of thing much and don't want things that I have to maintain and upgrade if I don't actually use them.
