I'm trying to find out if there's an iPhone or iPad app that can do the following.

I have the deck shuffled and cut and have a card chosen (no force) and secretly know it's identity. I open the app and say that it can reveal the chosen card. It does so.

Basically the app let's me somehow tell it what the chosen card was without the audience letting on.

My original idea was to be able to google the phrase "what card have we chosen" or something along those lines and have google name the card. I want to find out what apps are out there that might work along those lines.

alan rorrison has the same effect out called google trick!
