## What is Duometry?

How well can you judge an angle?

Duometry challenges you to match a target angle as closely as you can. Fold a compatible device or adjust the on-screen dial, lock in your guess, and discover how close you came.

Play solo over 5 or 10 rounds and aim for your best score.

Pass one device between 2–8 players for a friendly competition. Everyone’s guesses stay hidden until the shared reveal. Find out who came closest, compare scores, and keep playing.

Explore angles at your own pace with the dial. On hinge devices, Free Measure lets you read the device’s fold angle directly.

Come back for a daily challenge with three targets. Different daily modes put your angle intuition and visual memory to the test.
Play offline, with no account required.
