**Apple Watch Blood Oxygen Monitoring Returns: A Competitive Edge Restored**
Apple Watch users in the United States can celebrate as the Blood Oxygen monitoring feature makes its return after nearly a year-long absence. This comeback follows a patent conflict with medical technology firm Masimo, which resulted in Apple disabling the feature on new Apple Watch units sold in the U.S.
The latest update, implemented with the release of iOS 18.6.1 and watchOS 11.6.1, along with iOS 26 beta 7 and watchOS 26 beta 7, brings a fresh approach to Blood Oxygen monitoring. Instead of processing data directly on the watch, the Apple Watch now collects sensor readings that are analyzed by the paired iPhone. The results are shown in the Health app on the iPhone, rather than directly on the watch itself. This adjustment specifically applies to certain Apple Watch Series 9 models sold after a designated date, as well as all Apple Watch Series 10 and Ultra 2 models.
While this new approach may not be as smooth as the initial on-device processing, it effectively reinstates a vital health metric that numerous Apple Watch users had previously lost.
### Whoop’s Temporary Dominance
During the period without Blood Oxygen tracking on the Apple Watch, many users sought alternatives like Whoop. Renowned for its robust health insights, Whoop became a favored option for those looking for a non-smartwatch alternative. Its sleep tracking and recovery analytics are particularly praised for their performance, often surpassing Apple in these aspects. However, with the reintroduction of automatic SpO2 data logging on the Apple Watch, the competitive scene changes once more.
The revamped method enables passive background readings, meaning users can access SpO2 data without the need for manual checks. This feature is crucial for individuals who depend on continuous health monitoring.
### Apple Watch’s Comprehensive Utility
Despite Whoop’s advantages in sleep and recovery analytics, the Apple Watch persists as a more multifaceted device. It presents a broad array of functionalities, including fitness tracking, health metrics, notifications, payments, and various beneficial apps. There are signs that Apple is also looking to enhance sleep tracking features in upcoming watchOS updates, which could further reduce the disparity between the two devices.
With the Blood Oxygen feature reinstated, the Apple Watch reaffirms its position as a top choice for users interested in wearable health metrics. While Whoop continues to offer valuable insights for training and recovery without needing a smartwatch, Apple’s device now provides a more extensive set of features without requiring a subscription.
In conclusion, the return of Blood Oxygen monitoring not only bolsters the Apple Watch’s status as a capable health device but may also motivate users who previously relied on the old method to think about upgrading. With its all-encompassing capabilities, the Apple Watch remains a strong competitor in the health and fitness wearable market.
