As expected, Apple has rolled out the watchOS 9 update for Apple Watch users. This update brings in some new features and, most importantly, tries to improve the existing ones. The list includes new watch faces, improvements to the fitness app, a new medicine app, and more. Take a look at the details.

watchOS 9 gets new watch faces like Lunar, Playtime, Metropolitan and Astronomy. There's also the addition of new improved complications on dials like Utility, Simple and Activity Analog, along with background color editing for Modular, Modular Compact and X-Large for further customization. Portrait faces now support the depth effect on more photos and a focus will now appear on a selected watch face when launched on an iPhone.

The Workout app now has the ability to use the Digital Crown for the in-session view to easily see the workout views and now includes heart rate zones, which can be created manually to track the intensity of a workout. Users will now be able to create custom workouts and a new Multisport workout type, specifically designed for triathletes who can easily switch between different combinations of workouts.

Apple Watches can now support more running form metrics such as stride length, ground contact time and vertical oscillation. Additionally, they can match their results on a single route to see their progress. Swimming improvements include a new Kickboard detection to see when a user is swimming with a kickboard and the ability to track the user's efficiency with a SWOLF score.
