Age Guesser!

This app port a delightful meatspace card trick to iOS! That's right, if you thought a human guessing your age from a bunch of cards under audience scrutiny and time-pressure was impressive, imagine how jaw-dropping the experience is when done by a measly computer that only has 6 data points, and access to the internet, your social networks, etc.! It guesses your age!

It goes like this:
An ignorant unwashed peasant (or other participant) is shown 6 cards with a matrix of numbers, and indicates whether or not his or her age is on the card. Thereupon, the illusionist declares the age of said peasant before returning to his daily sisyphean hell of monotonous drudgery!!
