Your super slow Apple Watch will become way faster on Sept. 13

Along with the iPhone 7 and iPhone 7 Plus and Apple Watch 2, Apple announced watchOS 3 will be available for download on Sept. 13, the same day iOS 10 drops.

WatchOS 3 is a software update that no Apple Watch owner will want to miss. As we touched upon at WWDC in June, Apple's reworked some of the core functions to make launching apps significantly faster through a new "Dock" and deemphasizes the app grid screen.

In other words, as Mashable chief correspondent Lance Ulanoff said: It's a do-over for the Apple Watch and it's what the software should have been when the smartwatch launched last year.

Some other notable new features in watchOS 3 include a new Control Center that provides quick access to settings, activated by swiping up from the bottom of the watch face.

There's a new Scribble feature that lets you doodle drawings and write out text.

Apple's also built in better support for apps to be integrated as "complications" (basically widgets) into watch faces. And, of course, there are new watch faces including a Minnie Mouse to match the existing Mickey Mouse.

A new Breathe app also focuses on wellness by nudging users to breathe and meditate for short periods, similar to Watch's stand up reminder feature.

There's also a SOS feature that will allow users to contact emergency services instantly.
