Apple Returns Blood Oxygen Monitoring to the Latest Apple Watches

Apple has reintroduced blood oxygen monitoring to certain Apple Watch models in the U.S. by shifting the feature's calculations to the paired iPhone, sidestepping an ITC import ban stemming from its legal dispute with medical device maker Masimo. TechCrunch reports: Blood oxygen data will be measured and calculated on the user's paired iPhone, and results can be viewed in the Respiratory section of the Health app. This means users won't be able to view the data on their Apple Watch, as they'll need to do so on their iPhone. Apple says the update announced today is enabled by a recent U.S. Customs ruling, which means that the tech giant is allowed to import Apple Watches with the redesigned Blood Oxygen feature.

The change doesn't affect previously sold models with the original version of the feature or units bought outside the U.S. The redesigned feature only applies to Apple Watches that were sold after the ITC import ban took effect in early 2024. These users can access the redesigned Blood Oxygen feature through an iPhone and Apple Watch software update coming on Thursday.
