Apple watchOS 9 Gets Upgraded Sleep Tracker

The Apple Far Out event brought in many new products and upgrades, including new features to watchOS 9. The updated watchOS 9 brings in enhanced workout views, enhanced women's health updates, and more.

One of the new additions is the improved sleep tracking, which makes the Apple Watch and watchOS on par with competitors. The new feature determines when a user is in the REM (Rapid Eye Movement), Core, or Deep sleep stages of sleep.

The upgraded watchOS 9 gets this data from the accelerometer and heart rate sensor from the Apple Watch. Users can view data on their sleep stages on the dedicated Sleep app on the Apple Watch.

The Apple watchOS 9 also offers detailed information like the sleep duration based on the heart rate and respiratory rate. Users can tap into this data to compare different sleep stages via the Health app on the iPhone.
