FoldRush: Fold Counter

Fold, count, beat your record. Built for the iPhone Duo hinge.

FoldRush turns the hinge of your iPhone Duo into a game. Open, close, repeat: every full fold is counted live, with the hinge angle on a glowing ring.

FREE • Live fold counter with the hinge angle • 60-second challenge with your result and a shareable score card • Haptic tap on every fold

FOLDRUSH PRO (one-time purchase, no subscription) • All challenge modes: 10 s, 30 s, Race to 100 and Survival • Personal records and full history with session details • Charts: folds per day, week and all time • Hinge analysis: angle distribution, fold speed and duration • Clean, themed score cards without watermark • Home Screen and Lock Screen widgets • Accent themes and alternate app icons • CSV export of every session and fold

HONEST BY DESIGN iOS only shares hinge data with an app in the foreground, so FoldRush counts while it is open. Nothing is collected or sent anywhere: your folds stay on your phone.

FoldRush is made for iPhone Duo and needs iOS 27.1 or later. On other devices it opens, but there is no hinge to count.
