Apple has officially restored the Blood Oxygen app to its Apple Watch lineup in the United States after nearly eight months of absence. The feature, which was removed in January 2024 due to a patent dispute with medical technology company Masimo, will once again be available starting August 14, 2025.
Legal Battle and Resolution
The app’s removal stemmed from a legal battle over patented pulse oximetry technology. The U.S. International Trade Commission (ITC) had sided with Masimo, forcing Apple to withdraw the function temporarily. However, Apple has since reached a resolution, allowing the company to reinstate the app. While the terms of the agreement remain undisclosed, the decision marks a significant step forward for Apple’s wearable health technology.

Importance for Users
The Blood Oxygen app provides real-time monitoring of oxygen saturation levels, a key indicator of overall wellness and respiratory health. For many users, especially those with pre-existing health conditions, this feature offers peace of mind and valuable insights. Its return ensures that Apple Watch continues to stand out as a leader in consumer health technology.
Market Impact
Industry analysts expect the app’s return to strengthen Apple’s position in the smartwatch market. The removal had briefly dented Apple Watch’s appeal compared to rivals like Samsung and Fitbit, which continued to offer similar functions. Now, with the app back in action, Apple is poised to regain momentum, particularly among health-conscious consumers.
Looking Ahead
Apple has not confirmed whether future models will include redesigned hardware to avoid similar disputes. Still, the company remains committed to advancing health-tracking capabilities, signaling that health innovation will stay central to its strategy.
