About Intuii
Most games test what you know. Intuii tests how well you know what you don't.
Five estimation questions drop every day. How many piano tuners are in Chicago? How far is it to the Moon? You won't know the exact answer — nobody does. That's the point.
Enter your best guess, then drag out a range you'd bet 90% on. Too narrow and you'll miss. Too wide and you'll pay for playing it safe. Your confidence score reveals the gap between what you think you know and what you actually know.
Every player gets the same five questions each day. Track your streak and share your daily result card.

New in 1.4.0
Your daily five, now made for iPhone Duo.
- Open it sideways and the question and your range take one half, the number pad the other.
- Fold or unfold mid-question and you keep your place, guess and range intact.
- On shorter screens, Lock In slides up once your guess is in, and the keys hold still while you type.
- The Pro screen's close button stays put when you scroll.
- Old archive results show the exact question you answered, even ones we've since reworded.
