iOS 14 and macOS Big Sur are revealed in Apple's WWDC 2020. Another alongside these is watchOS 7 for Apple watch. The new watchOS iteration comes with most anticipated changes, including native sleep tracking and face sharing.
Native Sleep Tracking
After all this time using multiple third-party apps, you'll now be able to use native sleep tracking. The watch will track your sleep by tracking how you move, along with some ML to figure out if you're sleeping. The display will be turned off when tracking sleep, and you can tap on it to view the time.
You'll also be able to choose from a regular ringing alarm or a morning haptic alarm. In addition, your iPhone's Health app will have an updated sleep section that displays all of those metrics.
Watch Face Sharing
watchOS 7 introduces new complication capabilities. Although apps may have only one complication on a watch face, watchOS 7 lets a user put as many complications as they want from a single device. This way, for specific activities that you are interested in doing, you can customize your watch face. The selection screen was also redesigned in watchOS 7 regarding complications.
You can now share your watch face with others also through messages, or even social media. Additionally, watchOS 7 allows you to download faces watching from third-party apps, or even from websites.
In watchOS 7, the Workout app is getting updated, a new workout mode. This involves a new exercise on dance, practical strength training, and cooling down. The Activity app has also been redesigned and renamed 'Fitness' in the meantime. This will show up with the same name on your iPhone too.
Handwash detection is also to be added to Apple Watch with watchOS 7. With this, when you wash your hands the Apple Watch automatically detects and starts a 20-second timer. This is to ensure that you have the correct amount of time to wash your face.
