Guess Angle

73°. Looks easy. How close can you get? Pick a target angle, trust your eye, and take your turn. Live angle values stay hidden. Once everyone has locked in, see how close each person got. On iPhone and iPad, drag the orange pointer to match the target. On iPhone Duo with available hinge readings, unfold the phone and physically fold it to the angle you think is right. • Take turns with 1–8 people sharing one device, or try it on your own • Choose a random target or enter a whole number from 0° to 180° • Practice with a live angle readout and no scores • Save names and select your group next time • Each person starts fresh; all results are revealed together • Compare recorded angles and absolute differences, with ties shown equally • Try again with the same group or share the results English and Simplified Chinese. No account, ads, or in-app purchases. Names stay on the device; angles and results are processed locally. Result history is not saved. Requires iOS / iPadOS 27 or later. Physical folding requires iOS 27.1 or later and a device providing hinge readings. For fun, not precision measurement.
