As you might have guessed, iOS 11 isn't the only treat Apple has in store for its mobile device owners. The tech giant has also released watchOS 4, a major update to the Apple Watch that focuses on the health-conscious crowd. It includes many more workout types, lets you switch activities in mid-workout and will even sync with gym machines to provide consistent data. Also, heart rate monitoring is taking giant strides forward -- watchOS now provides a more detailed history of your heart rate, offers a view of your heart rate from your watch face and will warn you if there's a spike in heart rate when you're inactive.
There are plenty of improvements even when you aren't headed for your morning run. There's a slew of new watch faces, including a Siri face that provides context-sensitive info, a trippy Kaleidoscope face and Toy Story characters. You can browse apps in a easier-to-tap list instead of the usual grid, and the music app has been reworked with both a fresher interface and automatic syncing for Apple Music playlists. You'll also find hooks for Apple Pay Cash, although the money transfer feature won't be available until later in the fall.
A heads-up: watchOS 4 won't be available for your Watch until you install iOS 11, so be sure to do that first.
