Apple has reintroduced its Blood Oxygen tracking feature on the Apple Watch Series 9, Series 10, and Ultra 2 in the US after 18 months. The updated experience now requires two devices.
Editor’s Note: This matters because the return of the Blood Oxygen feature enhances health monitoring capabilities for users, reflecting Apple's commitment to health technology. The two-device requirement may also indicate a shift in how users interact with their devices.
