Apple is doubling down on making the Apple Watch the best health-tracking wearable out there and expanding features for its most demanding users — as well as everyone else. The next version of its watchOS will include a number of new health-related features, including the tracking of new metrics, automatic multisport tracking, improved sleep tracking and more.

iOS 16 will also bring the Fitness app to all iPhone users, not just those with an Apple Watch, as has previously been the case. It’ll track walking info and other metrics to approximate your fitness level.
