Hinged turns opening and closing your device into an experience. Fold it slowly and an old door groans. Flip it open and a chest of golden light sings. Every angle and every speed changes the sound, so no two openings are the same. Free to play • Creaky: an old wooden door with two rusty hinges. Open it slowly or fast; it's embarrassing either way. • Magic Chest: a slit of golden light that floods out as it opens. Aaaaaahhhhhhhhh. • Accordion: red bellows that stretch and squeeze. Open and close to play the chords. • Scream: your phone screams every time it moves. It hurts every time. Unlock more, one at a time • Airlock: crack the seal and vent steam through the hinge. • Sword: flick it open to draw the blade. • Mechanical: sci-fi doors that slide apart. Fully motorized. Allegedly. • Theremin: tilt the screens to play the pitch. Can't fold your phone? No problem. On any other device, place it face down on a table and lift it by its side. The phone's tilt becomes the hinge. Made with care • Sounds play the moment you move, following the hinge as it opens and closes. • Every page has its own animated scene that moves with the hinge. • Full VoiceOver support, Dynamic Type and Increase Contrast. • No ads, no accounts, no tracking. Swipe to pick a sound, then open and close to play.
