Blood Oxygen Monitoring Returns to Apple Watch in the US – With a Change
Apple Watch users in the US are finally getting blood oxygen monitoring back — but with a twist. After a legal battle with Masimo forced Apple to disable the feature last year, it’s returning via a clever workaround: your paired iPhone will now process the readings instead of the watch. The update applies to Series 9, Series 10, and Ultra 2 sold in the US, bringing Apple closer to Samsung’s health tracking game, though it’s a bit less convenient than before.
