Apple announced iOS 16 and watchOS 9 during its Worldwide Developer Conference (WWDC) back in June with plenty of new features for iPhone and Apple Watch.

A public beta of the both software builds have been available for a couple of months, but now the final versions are here and available to download. 

We have entire features on iOS 16 and watchOS 9, both of which give you a full run down of all the new features you can expect to appear on your devices. There's new Lock Screen customisation for iOS 16 that is one of the most exciting features to try and more advanced sleep tracking for watchOS 9, including sleep stages for Apple Watch, finally.

We've also got a piece on the first features to try on iOS 16 if you want to know the best ones to play with initially. With that in mind, here's how to download the software and try all the new things out.
