Swimming Enhancements
Since the Apple Watch is water-resistant, it’s the perfect companion for any workout you do, even swimming. And you won’t want to miss the new swimming enhancements coming to watchOS 9.
There’ll be a new feature called Kickboard detection, which will be added as a new type of stroke for the Pool Swim workouts.
The Apple Watch will be capable of detecting when you’re swimming with a kickboard and classifying the type of stroke.
Not only that, but if you’re an avid swimmer, you’ll also be able to track your SWOLF score, which is a score that takes stroke length, count, and the time you take to swim in the pool to determine your swimming efficiency. You’d want to aim at the lowest number possible, similar to golf.
