Zero telemetry, zero ads, no subscription, no account. 31 tools across five categories — Health, Environment, Travel, Utility and Smart — that open instantly and run completely offline on the watch itself.
Live heart rate with a rolling chart, your most recent HRV and resting heart rate, and a 0–100 Recovery Score blending last night’s sleep, HRV and resting HR against your baseline.
Guided breathing patterns with haptic phase cues that log Mindful Minutes to Health. Calibrate good posture once, then get a gentle nudge when you slump for five seconds or more.
Quick-pour buttons log water to Health and fill a daily goal ring. Caffeine tracking projects a bedtime half-life so a late coffee doesn’t wreck your sleep.
Elevation change and barometric pressure trend — a falling barometer hints at rain. On Series 10, the depth and water-temperature sensor for snorkelers and lap swimmers.
Compass with savable bearings and a turn-by-turn return arrow. Save your parking spot and the watch guides you back with a glowing arrow, or drop waypoints as you walk and retrace them in reverse.
Bubble level, protractor, multi-timer, Pomodoro, world clocks, tip splitter, unit converter, offline currency, dice, coin flip, QR codes and a flashlight with red night-vision and SOS modes.
Available now for iPhone, iPad, and Apple Watch.
