Once you wake up, you can view how much sleep you got last night on the Sleep app. Additionally, you can view your sleep trends for the past two weeks. The Sleep app on the Apple Watch Series 8 also offers Sleep Focus, which reduces distractions before you go to bed and ensures you don’t wake up with early notifications.
Apple Watch Series 8 brings all the sleep tracking features you get with older models, along with more detailed sleep insights thanks to the watchOS 9 update.
Along with these features, watchOS 9 on Apple Watch Series 8 unlocks improved sleep insights.

It then displays this sleep phase data in the Sleep app. You can also view more details, like sleep time and time spent in bed, along with additional metrics, like heart rate and respiratory rate, in the Health app on your iPhone.
The new Sleep Stages feature uses advanced machine learning models to detect if you are in REM, Core or Deep Sleep. As Apple explains, the . file “Machine learning models have been trained and validated against the clinical gold standard, polysomnography, with one of the largest and most diverse populations ever studied for wearable devices.” This new feature will soon be available on older Apple Watch models with the watchOS 9 update.
