I think is the most awesome app that i ever seen.
How does it work?
It's very simple! You think about a character (actor, your favorite hero from an anime, a singer ecc.) and then answer the questions of Akinator. In 10-15 questions Akinator can say what did you thinked about!
I tried this app several times, and it never failed, is totally awesome!
If you don't bealive me, try it!
