A free app for Android, by edurapp.

Magic Card is a game application for Android devices that allows you to perform amazing card tricks with a simple touch. It is based on the classic card game and it has been specially designed for phones with a proximity sensor, which is on the top of the screen next to the speaker of calls. If you have the same, you will have to run your hand over the phone and will occur the trick.

If you do not have it because it has such a tablet, the experience with this application will not be as good, but you can still perform their magic trick by touching the upper left corner of the letter.
