Fold On°: Angle Challenge

FOLDING PLAY REQUIRES IPHONE DUO WITH iOS 27.1 OR LATER. Other iPhones support the touch demo only; they cannot measure a fold. Turn the fold into the game. See a target angle. Fold your phone to match it by feel, then lock your guess. There is no live angle number to guide you. The reveal shows how close you came. After three rounds, the lowest total error wins. PLAY SOLO Chase a lower score across three guesses. Your best completed solo score stays on your phone. PASS THE PHONE Two players, one phone, the same target each round. Player 1's result stays hidden until Player 2 locks a guess. Six guesses settle the match, with a tie when the totals match. SHARE THE RESULT Export a score card with your total and round-by-round errors. Compare results or invite a friend to try. TOUCH DEMO ON OTHER IPHONES Drag an on-screen illustration instead of folding your phone. Demo scores are labeled and kept separate from physical-play records. The demo does not provide hardware angle measurement. SMALL BY DESIGN One focused game, bold violet-and-citron style, readable controls and support for larger text and Reduce Motion. Pay once. No ads, subscriptions or in-app purchases. No account required. Play offline; sharing uses the destination you choose. Records and preferences are stored locally. English only.
