CUPERTINO, Calif. - Apple has introduced a redesigned blood oxygen feature for some Apple Watch Series 9, Series 10 and Apple Watch Ultra 2 users through an iPhone and Apple Watch software update. Users with these models in the U.S. who currently do not have the Blood Oxygen feature will have access to the redesigned Blood Oxygen feature by updating their paired iPhone to iOS 18.6.1 and their Apple Watch to watchOS 11.6.1. Following this update, sensor data from the Blood Oxygen app on Apple Watch will be measured and calculated on the paired iPhone, and results can be viewed in the Respiratory section of the Health app. “Apple’s teams work tirelessly to create products and services that empower users with industry-leading health, wellness, and safety features that are grounded in science and have privacy at the core,” the company stated. The update was enabled by a recent U.S. Customs ruling. Apple Watch Series 9, Series 10, and Apple Watch Ultra 2 also offer users irregular rhythm notifications, the ECG app, Sleep Apnea Notifications, Fall Detection, sleep tracking, wrist temperature sensing, the Vitals app, the Noise app, the Medications app, and the Mindfulness app.
