iPhone

Fold it and the monster bites. Six monsters, six mouths, one very hungry hinge. There’s a monster in your phone. Close it, and a pair of silly eyes stares back at you from the cover screen. Tap them and they jump. Open it, and the inside display becomes a mouth. The jaws follow the hinge: fold the Duo a little and the teeth come together, snap it shut and it CHOMPS, with a crunch and a thump you can feel. Tap the mouth to bite, or drag to squeeze it shut. Pick your monster: • Cartoon: big purple grin and googly eyes • Softie: buck teeth and rosy cheeks • Organic: slimy fangs and a swamp-green hide • Mimic: a treasure chest with teeth, gold coins and a tentacle inside • Classic: a very human smile • Pumpkin: a carved jack-o'-lantern grin, lit from inside, seeds and all Every monster has its own eyes, its own teeth, its own sounds and its own inside. Tilt the phone and the face moves with you. No iPhone Duo? It works on any iPhone with iOS 27: tap the eyes twice and the mouth opens. Cartoon is free. A one-time purchase unlocks the other five monsters. No ads, no subscription, no account.

Snappier, smoother bites. Fold your iPhone Duo to a right angle and the monster chomps, and every bite now feels smoother.
