Apple Watch owners in the U.S. just got a big reason to update their devices. Apple just rolled out a redesigned Blood Oxygen feature to specific models, following a recent victory in a legal dispute. This change affects Apple Watch Series 9, Series 10 and Apple Watch Ultra 2 users who have been without the feature due to the ongoing battle.
Thanks to a U.S. Customs ruling, these users will soon be able to track their blood oxygen levels again, with a twist.
Instead of processing the data directly on the watch, the measurements will now be calculated on the paired iPhone and displayed in the Respiratory section of the Health app.

What this means for you
If you’ve been missing Blood Oxygen tracking on your Apple Watch due to the legal dispute, this is your green light to get it back. Updating today means you’ll once again have insight into your oxygen saturation, valuable for workouts, high-altitude trips and general wellness monitoring. This update ensures U.S. customers regain access to one of the watch’s most popular wellness metrics.
The Blood Oxygen app provides information for general fitness and wellness purposes only. It is not intended for medical use, self-diagnosis or consulting a doctor. Apple designed the Blood Oxygen app for users who are at least 18 years old.
Along with Blood Oxygen tracking, models like the Series 9, Series 10 and Ultra 2 offer irregular rhythm notifications, ECG, sleep apnea alerts, fall detection, temperature sensing and mindfulness tools.

Kurt’s key takeaways
Apple’s persistence in fighting for this feature shows how important health tracking has become for wearables. By adapting the technology to work around legal restrictions, Apple has kept its promise to prioritize user health tools.
