This app uses the Zener cards method.
Zener cards are cards used to conduct experiments for extrasensory perception (ESP), most often clairvoyance. In a test for ESP, the person conducting the test (the experimenter) picks up a card in a shuffled pack, observes the symbol on the card, and records the answer of the person being tested for extrasensory perception, who would guess which of the five designs is on the card in question. The experimenter continues until all the cards in the pack have been tested.
This app has two modes of making card deck: manual, when the experimenter chooses cards and there order. And random, when deck made of completely random cards.
