Apple is reintroducing blood oxygen monitoring on certain Apple Watch models after an intellectual property dispute.

Apple has announced the re-release of the blood oxygen monitoring feature for the Apple Watch Series 9, Series 10 and Apple Watch Ultra 2 models, after a US Customs decision allowed the feature to be reintroduced. It was previously suspended due to a patent dispute with the company Masimo. Users will be able to enable the feature through software updates. Apple continues to expand into health, recently adding sleep apnea detection and hearing health monitoring features.
