The Fake Psychic Test

Trick your friends, make new ones, or get free drinks at the bar with this sneaky app!
When you open the app, it starts out as a standard Zener Card ESP test. Five possible shapes are shown, and you must guess which one will come up next. You can use the app as a real ESP test, or be a jerk and trick your friends into buying you a drink.

INSTRUCTIONS (these aren't anywhere in the app so people don't suspect anything):

To activate cheat mode, press and hold on the face-down card for about a second, until you feel a very short vibration sequence. The number of vibrations tells you which mode you are in:

1 vibration: Normal mode2 vibrations: Always right mode--you'll look like a real psychic!3 vibrations: Never right mode--your friends will look like they are awful at this!

PRO-TIPS:

-Cheat mode works best if you really sell it. Put on a show! Take your time on your guesses and play up your "psychic abilities." If you're entertaining enough, people won't care that you're cheating.

-Don't do too many guesses in a row (keep it under 10), and don't repeat the trick, or people might catch on.

-Let the other person go first so they can see that the app works as advertised. Then, when they hand you the phone, very discreetly long-press on the middle of the screen. Do it very casually (maybe act as if you grabbed the phone from them wrong accidentally or use misdirection).

-Have fun!
