As part of watchOS 9, Apple has finally promised better sleep tracking for the Apple Watch. A sleep stage function will be included in the revised Sleep app. It will be able to detect and track the stages of REM, core, and deep sleep.
In the Health app on your iPhone, you’ll be able to see your sleep metrics alongside other statistics like heart rate and breathing rate. Participants in the health research initiative will be able to submit their sleep stage data to researchers from the Apple Heart and Movement Study.
One of the more noticeable health features of watchOS 9 is that it will display the length of time a wearer has been in atrial fibrillation (AFib). It will tell you when AFib is most active during the day or week.

The Health app will provide a full history as well as information on lifestyle factors that may have an impact on the disease, such as exercise, sleep, and alcohol consumption. To share with your healthcare providers, you’ll be able to obtain a PDF containing your AFib history and lifestyle factors.
The AFib history function was approved by the US Food and Drug Administration just last week. It’s only approved for people who are 22 or older and have been diagnosed with the disease in the United States.
Additionally, Apple is releasing a Medications app for iPhone and Apple Watch to assist customers in remembering to take their medications. For each drug, you can create individual timetables and reminders. Users in the United States will be notified of any medications they add to the Health app that have “potential important interactions.”
