App Description
Do you have extra-sensory perception (ESP)?
With PSI you can test and maybe train your ESP abilities. It is based on the classic scientific "zener card" test without cheating and biasing possibilities.
First the device selects a card and then you have to sense / predict, which card it is. The PSI Bar always shows you, how good you are doing compared to simple random picking.
PSI features:
- zener card test
- database for total statistics
- smooth animations
- lots of statistics
- hints to train your exra-sensory perception
