T heysay you can’t please all of the people all of the time, but Apple seems to have done just that with watchOS 9. The latest and best version of Apple’s wearable OS is packed with improvements across almost every aspect of the Apple Watch experience, and in many ways it delivers on the promises made in watchOS 8; its Focus modes are much more useful now, its workouts are much more customisable and deliver much more information, its sleep tracking is more detailed and its accessibility features are even better.
