Apple today released watchOS 3, the newest version of the operating system that runs on the Apple Watch. watchOS 3 is a significant update to the watchOS operating system, introducing an overhauled interface, new apps, new watch faces, and impressive performance improvements.
watchOS 3 can be downloaded through the dedicated Apple Watch app on the iPhone by going to General -> Software Update. To install the update, the Apple Watch must have 50 percent battery, it must be placed on the charger, and it must be in range of the iPhone. watchOS 3 is available for all Apple Watch models, but requires an iPhone running iOS 10 to install, which was also released today.
watchOS 3 features a new dock that houses your favorite and recently used apps so they’re quicker to access. Up to 10 apps saved to the dock are kept up to date at all times and are able to launch instantly, cutting down on app loading times.
Navigation is improved in watchOS 3, with left and right swipes able to change the watch face. Upward swipes bring up the Control Center, while a downward swipe opens the Notification Center. Pressing the side button brings up the new dock.
There are new Activity sharing features in watchOS 3, along with workouts and activities for wheelchair users. A new “Breathe” app guides you through daily deep breathing sessions to cut down on stress, and there are new Reminders, Find My Friends, and Heart Rate apps.
Three new watch faces are available, an SOS feature can automatically call emergency services, and an Apple Watch can be used to unlock a password protected Mac with new Continuity functionality. A revamped Messages app makes it easier to reply to incoming texts, plus there’s a new “Scribble” feature for writing replies on the Apple Watch face with a finger.
