Android mind reading app - use your Smartphone to perform this amazing psychic, mentalist trick

EFFECT: You ask a spectator to think of any number between one and 31. You explain that your Smartphone can be used to read minds. You ask a few simple questions, and then ask the spectator to touch your Android screen. When they do, the number that they just thought of appears on the screen.

 I guess you'll either love or hate this mind reading trick that you can perform with your Android device. Some of the comments about this app state that it's lame, and stupid and they figured it out right away. Really? Really!!???

If they figured it out right away, I believe it's because they recalled the paper method where the next box of numbers you chose depended on whether the previous one contained your selected number or not. Properly presented, the Android version is much smoother and more natural...and subsequently more amazing.

As with so many other magical effects, it's all in the presentation.
