Other wearables such as Garmin devices, Fitbits, and the Whoop band have advanced sleep tracking features for years now, but it will be Apple’s first attempt at it. If you want to see a detailed report, you can see in-depth sleep reports with respiratory rate data, and heart rate data on the Health app on your phone. Upon waking up, a graph of your sleep time and sleep stages will be available on your Apple Watch to view. During the event, Apple said that it used polysomnography-a benchmark for tracking sleep in clinical sleep studies- to train its machine learning. But with the upgrade, it’s going to show the user how long they were asleep, and the amount of sleep they got in every stage of sleep such as awake, REM, core, and deep by leveraging the Watch’s heart rate sensor, accelerometer, and some machine learning.

With the current configuration, the Apple Watch is limited to only showing the user an estimation of the hours they’ve slept. The improvements on the Apple Watch's sleep tracking front are only one of the few new health features on the Watch launching this year.

However, Apple is about to change that game with its WatchOS 9.Īnnounced on September 7, 2022, at Apple’s Worldwide Developers Conference, the Watch’s OS will get a significant upgrade that can track sleep stages, deep sleep, and how often you wake up at night. It was a simple tracker that got the basics covered, but it didn’t have all the bells and whistles that recorded every aspect of your sleep. In the past, you could download a third-party app on your Watch to track your sleep, but Apple launched its own sleep tracker with WatchOS 7. If you think you are not getting enough sleep or the quality of sleep is not that great, you can turn to your Apple Watch for help.
