Apple has made watchOS 3.0 available to the first-generation Apple Watch.
WatchOS 3.0 allows apps to update quickly both in the background and when launched so they display new content as soon as opened. The UI includes a new dock accessed by the side button, and a new control center accessed by sliding up from the bottom of the screen.
These new tools make it simpler to access apps and control toggles. Replying to messages now includes smart replies and scribbling directly on the screen. WatchOS makes it easier to switch and change watch faces; initiate workouts; and access notifications.
WatchOS 3.0 adds an SOS function that will automatically call 911 with a long-press of the button in times of need. The revised platform allows users to share fitness data throughout the day.
A new app included in WatchOS 3.0 called Breathe can be used to schedule and perform deep-breathing and calming exercises. WatchOS 3.0 is free to download. It requires an iPhone and 50% charge on the Watch.
