I actually asked a bunch of psychologists about this. Most people will either freeze or run. If your inbuilt reaction is to run, you are already in the lucky group. The goal is to use it, if possible, while running, so I tried to make it as simple as possible to activate. Unfortunately, because of Apple restrictions, you still need to launch the app, but I'm experimenting with things like using notification center for faster access

Cool. I'm not sure if your part of the community already but if it's open source etc you should post it on the Stamford University Liberation Tech mailing list.

Talk about an edge case for UI design :). I watched a show about a cop who couldn't open his trunk with his keys while he was under fire.
