In Stopwatch Loop Mode, the "FIX to 10" button now disappears 16 seconds after starting, allowing correction of accidental taps. ### 26.01.10 — 2026-01-12 The adjustment of the Watch app could not reach the practical level, so I gave up developing it. Fixed a bug in frame conversion. ### 25.12.22 — 2025-12-22 In previous versions, you can now use shortcuts to control the volume of incoming calls and the volume of the device.
