Blood Oxygen

With the Blood Oxygen app on Apple Watch Series 6 or later*, you can measure the blood oxygen saturation levels directly from your wrist. Using the blood oxygen sensor on Apple Watch, the Blood Oxygen app can help you assess oxygen levels in your blood and get insights into how well your body is absorbing oxygen and overall wellness.
