Guess Angle

73°. Looks easy. How close can you get? Drag the orange pointer on an ordinary iPhone or iPad. On iPhone Duo with available hinge readings, physically fold the phone from your current position. No need to fully unfold first. Live angle values stay hidden until you lock in. Try it on your own or take turns with friends matching the same angle. Once everyone has confirmed, see how close each person got. • Me is selected by default for a quick start; add and select friends for 1–8 people sharing one device • Pick a random target or enter a whole number from 0° to 180° • One confirmation per person; smaller errors rank higher and ties share a rank • Streak challenge: stay within ±5° to score a point and continue; one miss ends the run • Practice with a live angle readout and no scores • History shows the local scoreboard and recent rounds, including multiple results from the same person • Expand a round for its results, then save or share a score card in your choice of style Names, completed round records and challenge bests stay on this device. Round history can be cleared. Renaming or removing a friend does not rewrite names in completed records. English, Simplified and Traditional Chinese, Japanese, Korean, Spanish, French, German, and Portuguese (Brazil). The app follows your device's per-app language preference. Requires iOS / iPadOS 16 or later. Physical folding requires iOS 27.1 or later and a device providing valid hinge readings. Other devices use the touch pointer. No account, ads, or in-app purchases. Data is processed locally. Results are sent to another app or service only when you choose to share. Saving a score card requests add-only Photos permission.
