Apple Watch Series 10 vs Series 9: how big are the differences?

In this article, we’ll specifically look at the health features of the Apple Watch Series 10 vs Series 9 to see what’s new.

Apple Watch Series 10 vs Series 9

By far the most important addition this year when it comes to the Series 10’s health features is sleep apnea detection. Only the Series 9 and the Ultra 2 have also received this function. As usual, more new health and fitness features are coming with watchOS 11, running on Series 6 and above.

If you have the Series 10, Series 9, or Ultra 2, you can ask Siri for updates to your personal health information. You can also securely record new health data via voice, such as your weight, a medicine you’ve taken and more. If you already have a Series 8, that’s the only health feature you’re missing. If you have a Series 7 or older, you get more health features with the Series 10 or Series 9.
