  • Apple Watch Series 6 might be getting another lifesaving feature.
  • Code snippets in iOS 14 suggest blood oxygen monitoring is coming.
  • It isn't clear whether the feature will be available on older watches.

Apple Watch Series 6 might be set to get a big new health feature, according to a new report. Blood oxygen level monitoring could be coming to Apple Watch if code snippets found in iOS 14 by 9to5Mac are any indication.

Apple has been rumored to have plans to add blood oxygen level monitoring before, but this is the closest we've come to proof that it's actively being worked on.

Keeping tabs on the amount of oxygen in our blood can be important, with levels of between 95% and 100% deemed to be acceptable. Anything below that can cause impaired judgment and a general feeling of being unwell, while anything below 80% can be a real issue. If the issue is prolonged there's a risk of heart attack and worse.

While 9to5Mac has spotted something in iOS 14 that suggests blood oxygen monitoring is coming, it isn't clear yet whether it will be possible using the existing Apple Watch suite of sensors. If it isn't, the feature will be exclusive to Apple Watch Series 6 which is likely to be announced in September.

With Fitbit and other fitness bands already offering blood oxygen level monitoring, it's a big miss for Apple. It's surely a matter of when, rather than if, Apple will add it to Apple Watch.
