Auto Sleep - Sleep Watch

Auto Sleep automatically tracks your sleep using Apple Watch — no buttons to press, no setup needed. Just wear your watch to bed and wake up to a complete picture of your night.

AUTOMATIC SLEEP TRACKING
Sleep tracking should be effortless. Auto Sleep detects when you fall asleep and wake up using your Apple Watch sensors. There's nothing to start or stop — your sleep data is waiting for you every morning.

SLEEP RINGS
Three beautiful rings show your progress at a glance:
- Duration Ring: How long you slept vs. your goal
- Quality Ring: How efficient and restful your sleep was
- Consistency Ring: How regular your sleep schedule is

SLEEP FUEL SCORE
Your Sleep Fuel score (0-100) combines duration, efficiency, deep sleep, and REM sleep into one easy-to-understand number. Know exactly how well you recharged overnight.

READINESS SCORE
Start each day knowing how ready your body is. The Readiness Score factors in your sleep quality, heart rate variability, and resting heart rate to tell you if you should push hard or take it easy.

DETAILED BIOMETRICS
Monitor your body through the night:
- Heart Rate: Min, max, and average overnight heart rate
- HRV: Heart Rate Variability tracking for recovery insights
- Blood Oxygen (SpO2): Oxygen saturation levels during sleep
- Respiration Rate: Breathing patterns throughout the night
- Noise Levels: Environmental audio monitoring

SLEEP STAGES
See exactly how your night breaks down:
- Deep Sleep: The most restorative stage
- REM Sleep: Critical for memory and learning
- Core Sleep: Light sleep transitions
- Awake: Brief nighttime awakenings

SLEEP CLOCK
A beautiful circular clock face maps your entire night visually. See sleep stages as colored arcs around a 12-hour dial with bedtime and wake time at a glance.

SLEEP BANK
Track your sleep surplus or deficit over time. The Sleep Bank shows whether you're getting enough rest or building up sleep debt that needs repaying.
