apple watch sleep tracking watchos 9
Apple enhanced the built-in Sleep app on the Apple Watch in a big way in ‌watchOS 9‌, introducing Sleep Stages. With Sleep Stages, the Apple Watch is able to tell you how much time you spent in REM, Core, or Deep sleep during the night, along with the amount of time that you were awake.

You can also compare this data with the heart rate, respiratory rate, and (on Apple Watch 8 and Apple Watch Ultra models) wrist temperature measurements that your Apple Watch can take throughout the night.

To begin tracking your sleep with Apple Watch, you need to set up a sleep schedule on your iPhone or Apple Watch. The following steps show you how it's done.

How to Set a Sleep Schedule on iPhone

  1. Launch Apple's Health app on your ‌iPhone‌.
  2. Tap the Browse tab in the bottom-right corner of the screen.
  3. Scroll down and select Sleep.
  4. Tap Sleep Schedule under "Your Schedule".

  5. If Sleep Schedule is off, tap the switch to toggle it to the green ON position.
  6. Under "Full Schedule," tap Set Your First Schedule.
  7. Tap any of the blue circles under "Days Active" to disable Sleep Schedule on any days of the week.
  8. Using your finger, drag the ends of the sleep block to extend it around the clock graphic. This sets your sleep goal as well as your bedtime and wakeup time.
  9. Scroll down to reveal your Alarm options. Use the switch next to Wake Up Alarm to turn the alarm on/off. If you enabled the alarm, you can select the vibration type and sound you'd like to hear using Sounds & Haptics, adjust the volume using the slider, and allow for a snooze using the Snooze switch.
  10. Tap Add in the top-right corner when you're done.
  11. To add a different schedule for different days (the weekend, for example), tap Add Schedule for Other Days and customize your options as described in the previous steps.

  12. Note that if this is your first time setting up a Sleep Schedule, after opening the Health app and navigating to the Sleep section, you'll need to tap on "Get Started" and set a sleep goal before you can set and adjust your sleep schedule.

  7. Use the switch next to Alarm to turn the alarm on/off. If you enabled the alarm, you can select the vibration type and sound you'd like to hear using the Sounds & Haptics button. Note that if your watch is in silent mode, your alarm will be replaced by a tap on the wrist.

  8. Your suggested bedtime is based on your Sleep Goal, which you can edit by using the back button to return to the Full Schedule menu screen. From there, swipe down and tap Sleep Goal, and adjust the hours and minutes to suit.
