Turn your Apple Watch Digital Crown into a pocket fidget toy. Every click syncs haptics, sound, and motion — like wrist ASMR. Silent mode for meetings. Headphones for the full sound. No account. Crown Calm turns your Apple Watch Digital Crown into something you can play with anytime. Each turn brings a synchronized response in haptics, sound and visuals. Explore 30 scenes, including a fidget spinner, rain on glass, clockwork, bubbles, an abacus, a mechanical keyboard, forests, distant thunder, whale song and a night train. Snowfall, kalimba and wind chimes play public-domain melodies like a music box. Play three crown-controlled games: move the paddle for ping-pong keep-up, charge a basketball shot, or rotate a marble maze to find the exit. A one-minute breathing experience follows the opening and closing of a flower. Turn the crown to adjust the pace. Switch sound and haptics on or off separately. Quiet mode lets you turn silently. Reopen the app with headphones connected to enable audio automatically, except in Quiet mode. Touch and hold a scene to favorite it. Supports 12 interface languages. No account required, no developer-side data collection, and no access to health information. This app provides sensory play and breathing experiences; it does not provide medical diagnosis or treatment.
