watchOS 9 may feature “major upgrades to activity and health tracking”

In the new version of watchOS 9, which is expected to be launched next, Apple is expected to further improve the tracking effect of sports and health data, so that the Apple Watch can more accurately record the user’s physical state.
As for the design part, Apple may change the existing arc curve design of the Apple Watch and may introduce a flat right-angled line design similar to the iPhone 12 series. However, to make such adjustments in the relatively small internal space of the Apple Watch will actually face greater challenges, so Apple may still continue the existing design language of the Apple Watch, and may only make adjustments in details such as size and usable area.
