WatchOS 7: All the cool new Apple Watch features unveiled at WWDC

At its annual Worldwide Developers Conference on Monday, Apple unveiled the next major release of its wearable OS, WatchOS 7. WatchOS 7 adds much-anticipated sleep tracking features, including a Wind Down mode to help you get to bed on time. When you wake up, you'll see a visualization of your previous night's sleep, including periods of wake and sleep, and a chart showing weekly sleep trends.

While the watch lacks a watch face store, the new software adds the ability to share customized watch faces and complications. If a shared watch face uses apps you don't have, you'll be able to download them easily. You can also easily share a face you've created yourself with a contact, or across social media.

In terms of health and fitness, WatchOS 7's Workout app adds support for four new workouts: core training, dance, functional strength training and cool down. The Activity app where you track your workouts will now be called Fitness, and will include a new Summary tab that gives you an easy way to see your activity history, workouts and trends, all in one view.

With WatchOS 7, you'll be able to use Siri to translate several languages directly from your wrist. Like on iOS 14, in the Apple Maps app on WatchOS 7, you'll be able to see cycling-specific directions on your watch in some cities.

Amid the coronavirus pandemic, WatchOS will use machine learning to determine when you start washing your hands, and sets a timer so you know you're getting the recommended 20-second wash.
