🩸 Make it better with O2 Buddy: apps.apple.com/us/app/o-buddy/id6751239297
Apple has officially brought back the Blood Oxygen feature on select Apple Watch models in the U.S.—but it works a little differently now. In this video, I break down everything you need to know about how the feature has returned, what models are supported, what the new limitations are, and how Apple pulled this off via a clever software workaround in iOS 18.6.1 and watchOS 11.6.1.
This update is available for Apple Watch Series 9, Apple Watch Series 10, and Apple Watch Ultra 2 — but only for those sold in the United States that originally didn’t have the Blood Oxygen app enabled. Instead of calculating blood oxygen directly on the watch, the new system uses the paired iPhone to process the sensor data, with results now showing up in the Respiratory section of the Health app.
00:00 - Intro: Blood Oxygen is back… kinda
00:42 - Why this feature was removed in the first place
01:31 - Apple’s legal workaround explained
02:15 - Which watches are affected?
03:06 - How the new system works
04:02 - iPhone handles the calculations now
04:43 - What’s missing in this new version?
05:35 - Why the change doesn’t affect all users
06:24 - Will this feature come to older watches?
08:12 - Final thoughts & what Apple might do next
