Rypeater is a watchOS-only minute repeater experience for Apple Watch. Wind the Digital Crown to charge the repeater, then listen as the app chimes the current time with separate sounds for hours, quarters, and minutes. A built-in complication lets you open directly into winding mode from the watch face. Rypeater is designed as a quiet, mechanical-inspired timepiece interaction for Apple Watch.
