How it uses iPhone Duo

Reads the hinge as the phone opens and closes; a random fold triggers a simulated crack spreading from the crease, with additional folds adding visual effects.

App Store descriptionWritten by the developer.

CrackGate turns your folding phone's hinge into a glass-crack effect toy. Pick a picture, tap Start and begin folding. CrackGate reads the hinge as you open and close, building the tension with soft creaks, faint glass crackles and little haptic ticks. Keep going and, on a random fold, it gives way: a sharp CRACK, a strong haptic hit, and a shattered-glass effect spreading out from the crease. It doesn't stop there. Every extra fold adds more: new glowing lines, a dark ink blot that slowly spreads, and a glitchy flicker on the front screen. It's all on-screen visuals and sound. Your display is perfectly fine, and you can go back to the start screen any time by holding the top-left corner for one second. FEATURES • Real hinge sensing: the effect builds as you fold • Real recorded glass sounds and layered haptics • Three levels: Mild, Spicy and Doomed • Use any photo, or your own screenshots, for the inside and front screens • Front-screen glitch you can turn on or off • Built-in wallpaper if you'd rather not pick a photo Made only for phones with a folding display. It needs a real hinge to work. No accounts, no ads, no data collected. Made by Hot Dang Studio · hotdang.studio
