Postcognition
The answer is picked before you tap. Can you sense what is already hidden? In ESP research this is the classic clairvoyance setup: the target exists, you just cannot see it.

Every correct guess grows your streak. Beat your best and watch the odds shrink.
Two ways to test your sixth sense
Precognition
The answer is picked only after you tap, so nobody knows it in advance, not even the app. Can you predict what is about to happen?
How rare is your streak?
Next to your streak, Intuitio shows the chance of getting one more answer right in a row by pure luck. Each extra correct answer halves the odds with 2 options and divides them by four with 4 options.
- 3 in a row, 2 options
- 12.5%
- 1 in 8
- 3 in a row, 4 options
- 1.6%
- 1 in 64

Frequently asked questions
Is Intuitio free?
Yes. Intuitio is free to download and play, with ads. An optional Intuitio Premium subscription, monthly or yearly, removes all ads.
How is the streak probability calculated?
It is the chance of guessing one more answer in a row than your current streak by pure luck: 1 divided by the number of options, raised to the power of one more than your current streak. With 4 options and a streak of 2, that is 1 in 64, about 1.6%.
What is the difference between precognition and postcognition?
Timing. In postcognition the right answer is chosen before you tap, so you are trying to sense something hidden. In precognition it is chosen after you tap, so you are trying to predict the future.
