Is there an app that will replace the non working blood oxygen sensor on the new apple watches?
Apple Watch Ultra
No. Apple cannot allow the tech to be used on US watches, whether with Apple's app or someone else's.
M1 Mac mini, macOS 14.5; Watch, series 7 GPS/cellular, watchOS 10.5; iPhone 12 Pro, iOS 17.5; TV 4th Gen, tvOS 17.5; HomePods, audioOS 17.5 and Airport Express w/ Airplay 2
The patient violation ruling by a federal judge was in relationship to the hardware used, not the software. Thus hardware on models sold in US is disabled. The ruling only applies to Apple Watches sold in US.
That seems rather extreme.
I believe that a watch bought outside the US with functioning Blood Oxygen and then brought to the US, the function will be disabled with the first US update.
That's probably what happened to mine. It was bought in 2023 but I just activated it yesterday and there was an update. I'm having numerous issues with it so I'll be visiting the Apple store Monday.
