An App That Recognizes You

Here's one!



So if you see someone aiming a phone at you and going through all the other motions, don't do anything. Because by then it's too late.

That's be a good one for church. You have a phone rigged over the door. Some stranger comes in, you call them by name, and they think it was divine revelation.

Or a bar. Like one "where everyone knows your name." Maybe they didn't know it five minutes ago, but they know it now that you're here.
