Blood oxygen detection won’t be available on Apple Watch Series 10 in the U.S.

Apple Watch Blood Oxygen sensor and app measure the oxygen saturation of blood so users can better understand their overall fitness and wellness.

Apple’s Blood Oxygen app can allow you to measure the oxygen level of your blood on-demand directly from your Apple Watch, providing you with insights into your overall wellness. However, due to a legal dispute, the Blood Oxygen app is only available in certain countries and regions and is supported on Apple Watch Series 6 and later, and any model of Ultra, with some restrictions on watches purchased in the United States.

The blood oxygen feature, introduced with the Apple Watch Series 6, will not be present on Series 10 models sold in the U.S. However, the rest of the world will be able to access the health feature on the new watch.
