Understand how sleep affects your day
Advanced sleep tools estimate light, deep, and REM time using heart rate and motion. Enough time in each stage supports memory, physical recovery, and next-day focus.
How tracking works overnight
Wear the watch to bed. Heart rate and movement sensors run in the background; in the morning, open the app for a sleep score and stage breakdown compared with your recent baseline.
Features that support better rest
- Sleep tracking each night with trend charts.
- Sleep schedule and bedtime reminders.
- Silent vibration alarms that can target lighter sleep phases on supported models.
- Optional smart wake to reduce grogginess.
Tips for accurate nights
Charge before bed if battery is low. Keep Bluetooth connected if you want notifications and full sync. Unconscious wrist raises while sleeping may be filtered—raise the screen with the display facing up if raise-to-wake seems inconsistent.
Shop cuff wearables
Compare oscillometric wrist models with inflatable cuff technology.
