It woudl be great to have an app that would be your eyes and ears in the event of an emergency.  It would be hard to try to dial 911 when being attacked or when assaulted from out of the blue.  Here's how I think it would work: 

• Unlock your phone (iOS with thumb)
• If you don't respond with "normal behavior" after unclocking your phone, and/or you don't respond to a notificaiton asking if there is an emergency
• The camera, mic and recording of location kicks in 
• A robo call is made to 911 automatically (or some emergency service is pinged)

This would make a lot of parents feel better in the event that a child is attacked and they can't call.  It could even be like the "tap" apps that "tap" to unlock computers, etc... there could be a "tap" on the phone to start the app.&nb
