Circadian Rhythm: Body Clock

Morning light, coffee timing, deep work, wind-down: build a daily routine timed to your body clock and sleep better tonight.

Sync your day with your body clock. Circadian Rhythm shows when your body is wired for energy, focus, training and sleep — and builds a simple daily routine around it.

YOUR CIRCADIAN CLOCK See your whole day on one 24-hour clock: cortisol rise, morning sunlight, cognitive peak, afternoon dip, highest body temperature, melatonin rise and more — all timed to your own wake-up and bedtime.

A DAILY ROUTINE THAT FITS YOU Pick the habits you want — morning light, coffee timing, deep work, exercise, last meal, wind-down, screens off — and every action is scheduled around your personal rhythm, with gentle reminders.

CIRCADIAN SCORE One daily score built on sleep timing, sleep duration, morning light and your routine, with a clear tip on what to improve next.

SLEEP INSIGHTS Track bedtime and wake-up consistency, see how close you are to your goals, and spot trends over 7, 30 or 90 nights. Syncs with Apple Health.

APPLE WATCH, WIDGETS & LIVE ACTIVITIES Your protocol on your wrist, on your Home and Lock Screen, and in the Dynamic Island. Apple Watch can even check off your morning sunlight automatically.

REAL SUNSET, EVERY DAY Sunset and sunrise follow your location and the seasons, so evening wind-down always lands at the right time.

Science-based and private: your data stays on your devices.
