Echo brings a wooden fish and a virtual prayer wheel to your wrist. 【Now on iPhone】 Knock on your phone: a large wooden fish with sound and haptics, ready to sit flat on any desk. Merit syncs in real time with your Apple Watch — knock on the watch, hear it on the phone. Six fish styles, six knock sounds, custom floating text; a 12-week knock heatmap, daily streak stats, immersive mode and keep-awake. Designed for Apple Watch, Echo responds to movement, touch and the Digital Crown with sound and haptic feedback. No iPhone companion app is required to use it. PRAYER WHEEL Turn the Digital Crown, or raise your forearm and trace circles while keeping your fist facing roughly the same direction. The virtual wheel responds to your movement and keeps spinning with inertia. Choose from five themes inspired by Guanyin, Medicine Buddha, Manjushri, Dzambhala and Kangyur. The Guanyin wheel is available by default. Unlock other styles for free through achievements, or make an optional one-time in-app purchase to unlock all prayer wheel styles immediately. Restore Purchases is available in Settings. WOODEN FISH MODES Motion: strike through wrist movement, with three sensitivity levels. Manual: tap the screen or turn the Digital Crown to count strikes. Steps: start a walking session to turn steps into a virtual merit count. YOUR OWN PACE Set a per-round goal and follow your progress on a ring, or choose an unlimited session. Personalize your experience with six wooden fish designs, six sound choices, custom floating text and a mute option. WRIST-SIZED RECORDS See daily activity on a heatmap in Settings, add today's merit count to a compatible watch face, and show, hide or reorder mode pages. With your permission, mindfulness records can sync to Apple Health. A pure-black interface made for a small screen. Requires Apple Watch with watchOS 10.6 or later. Step and Health features require the relevant permissions. Echo offers virtual interactions and personal records. It does not promise spiritual outcomes or provide medical diagnosis or treatment.
