Apple has ultimately revamped and reintroduced the Blood Oxygen feature on the Apple Watch Series 9, Apple Watch Series 10, and Apple Watch Ultra 2 in the United States. This functionality monitors the percentage of oxygen that your red blood cells transport from your lungs throughout your body, and it can be remarkably beneficial for understanding your overall health.
Utilizing applications like Gentler Streak, having access to the blood oxygen measurement aids you in gauging your readiness for a new day of exercises or alerts you if you are on the verge of falling ill. Although this feature does not have FDA approval like the ECG app on the Apple Watch, it remains a valuable wellness tool, and we will share how to maximize its use.
Whether you overlooked the Blood Oxygen app on the Apple Watch prior to its removal or you were excited to witness its return in iOS 18.6.1 and watchOS 11.6.1, we are here to guide you on how to utilize the feature on your Apple Watch and how to locate the pertinent metrics on your iPhone.
