Apple Watch Blood Oxygen Feature

Apple has reintroduced its Blood Oxygen feature through a new software update, rolling out with iOS 18.6.1 and watchOS 11.6.1. This update restores functionality for Apple Watch Series 9, Series 10, and Apple Watch Ultra 2 users. The return of this feature follows a patent-related dispute that had temporarily limited access.

Apple first launched the Blood Oxygen sensor in 2020, during the Covid-19 pandemic, when monitoring oxygen saturation became a vital tool for understanding respiratory health. The technology quickly gained popularity for providing insights into wellness directly from the wrist.

How Users Can Access the Redesigned Feature?

Apple has made the process simple for eligible users. By updating their iPhone to iOS 18.6.1 and Apple Watch to watchOS 11.6.1, the Blood Oxygen app can be reactivated. In this updated version, data from the Apple Watch is sent to the paired iPhone for processing, with results stored in the Health app under the Respiratory section.

This seamless integration ensures that users not only regain access to the feature but also benefit from improved accuracy and centralization of their health data.

Apple’s Commitment to Health and Wellness

Apple emphasizes that its mission is to provide health and wellness features that are backed by science, with user privacy at the core. The Blood Oxygen app is just one example of Apple’s broader ecosystem of tools designed to help users monitor their overall well-being.

Alongside the Blood Oxygen feature, Apple Watch Series 9, Series 10, and Ultra 2 also include 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. Together, these features make the Apple Watch one of the most comprehensive consumer health devices available today.

Why the Blood Oxygen Feature Matters?

Blood oxygen measurement is more than just a number. Low oxygen levels can signal underlying respiratory or cardiovascular concerns. Having this information readily available empowers users to take proactive steps toward their health. Whether it is monitoring recovery, tracking wellness trends, or simply staying informed, the feature offers valuable insights.

Conclusion

The return of the Blood Oxygen feature highlights Apple’s ongoing effort to deliver meaningful health tools to its users. With the latest updates, Apple Watch owners once again have access to an important wellness metric, seamlessly integrated into their daily health tracking. By combining innovation, user privacy, and science-backed technology, Apple continues to strengthen its position as a leader in personal health monitoring.
