Classic ESP Test is a fully-functional implementation of the classic 'Zener' ESP test.

In Telepathy mode, all symbols are displayed to the telepathic sender at once so the subject can't mistakenly use their keen sense of clairvoyance to demonstrate telepathy as well. Of course, if the telepathic sender wants help with a random selection; a simple double-tap will give a very subtle and brief suggestion.

Unlike some other ESP tests available, this app actually displays the graphics while you use clairvoyance to determine what is being displayed.
The clairvoyance test can be used with two people or just one. In the case you are taking as well as administering the test, you will need to hide the phone from your sight at the beginning of each test. The phone will give you about seven seconds after which time it will play a chime and display the symbol you are to clairvoyantly retrieve. When you have decided your answer, look at the phone and press the corresponding button. The next trial will commence immediately!

I plan on ramping up the production on this one so it might not be at this price forever: Get it now!
