Fold your iPhone Duo and turn the outer screen to your child: they watch a paper puppet show while you play the puppets, follow the story cards and catch their laugh on the inner screen. Works on every iPhone, too. ON iPHONE DUO Fold the phone and turn the outer display toward your child. The stage fills the outer display, so your child watches the show while you keep the puppet controls, the story card and the camera monitor on the inner display. You see your child's face and never miss the look they make when the wolf appears. Your child sees no buttons. HOW IT WORKS Each thumb leads one paper puppet. Slide it to walk, tap an action and the puppet bows, hops or waves, just like a rod puppet on a stick. Story cards prompt you scene by scene: who comes on stage, what happens next, and a question that gets your little audience talking. The voice and the imagination are yours. One tap on the shutter button saves the moment as a photo. WHAT'S INSIDE • Three classic tales you already know: Little Red Riding Hood, The Three Little Pigs, The Tortoise and the Hare • Paper-style puppets, forest and cottage scenery, day and night lighting, props the puppets pick up • Story cards in five languages: English, Czech, Spanish, German, French • Sound effects, a gong and applause, or play in silence • Free play with any puppet and any scenery • Photos from the show are saved to your Photos library, and you see them all when the curtain closes MORE STORIES Add the Winter Tales pack with three more tales: The Snow Queen, The Nutcracker and The Elves and the Shoemaker. Or the Sea Tales pack: Captain Whiskers and the Whale’s Yawn, The Golden Fish and The Little Mermaid. Both are in-app purchases. NO SCREEN TIME TRICKS No ads, no accounts, no tracking. Nothing is collected and nothing leaves your phone. The camera image is never recorded; photos go only to your own Photos library. On iPhone Duo your child sees only the stage: no text, no buttons, no feed. ALSO ON iPAD AND OTHER iPHONES On iPad the stage and the controls sit side by side in landscape, or one above the other in portrait; on a regular iPhone the stage is at the top and the controls below. Sit next to your child or prop the device up, play, and catch the reactions with the front camera. Pocket Stage requires iOS 27. The outer display is available on iPhone Duo; the photo button works on every iPhone.

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.
