watchOS 3 released alongside iOS 10 with a bunch of new features, core technologies and user interface enhancements. With watchOS 3, navigating your watch is now intuitive, as it should have been from the onset. A new Dock feature lets you access your frequently used apps with a press of the Side button and they load way faster, even on the original watch.
Apps can also take advantage of Background App Refresh technology to stay up to date, Messages now supports stickers, enhanced Digital Touch features and even fullscreen and bubble effects, like in iOS 10, plus tons more.
