Apple has announced the next version of its watchOS operating system will be available to all Apple Watch owners starting on September 19th.
As Apple has done with watchOS in the past, it’s focusing on the operating system’s fitness tracking features. WatchOS will include a redesigned workout features, new features aimed at swimmers and smart activity coaching.
The company has also reworked the heart rate app. Apple Watch will now display both the user’s resting and recovery heart rate right on the wearable’s watch face. With watchOS 4, the Apple Watch will notify the user when their heart rate becomes elevated but they appear not to be moving. In addition, watchOS 4 will be able to detect irregular heart beats, as well as afib and sleep apnea.
While it didn’t talk too much about watchOS 4’s non fitness features, the company says other features are including in the update. For instance, the company promised a redesigned music experience.
