Apple confirmed the official release date of watchOS 4 at a media event held today at the Steve Jobs Theater at Apple’s headquarters in Cupertino. watchOS 4 will be released on Tuesday, September 19th.
Announced at WWDC in June, watchOS 4 features new watch faces including a Siri watch face that displays personalized information based on the time of day, Toy Story and Kaleidoscope faces, motivational notifications to inspire you to close your Activity rings, a new Workout app interface, automatic syncing with curated Music playlists, a dedicated Apple News app, and more.
Apple hasn’t announced a Golden Master seed of watchOS 4 yet, but it will presumably be released to developers later today. Usually the last developer release before a public launch, the GM seed will allow developers to finalize their watchOS 4 apps and submit them to the App Store for approval before watchOS 4 is released publicly.
