watchOS 9: New fitness metrics, sports modes, health features, updates & more

While Apple announced watchOS 9, the successor to watchOS 8 for Apple Watch 8 and earlier at WWDC 2022 it's also announced a release date of September 12 at the ‘Far Out' event from September 7.

It's an all-new look for the new Apple Watch Ultra, Apple Watch 8, Apple Watch SE 2 and earlier wearables from Apple – although the Apple Watch 3 will no longer be supported, despite still being on sale – and brings improved running metrics, better sleep tracking, more medical capabilities and loads more watch faces too.
