Footnote
* Blood Oxygen app measurements are not intended for medical use, including self-diagnosis or consultation with a doctor, and are only designed for general fitness and wellness purposes.
** The ECG app is available on Apple Watch Series 4 and later (not including Apple Watch SE) with the latest versions of iOS and watchOS. See apple.com/watch for compatibility details. ECG is not intended for use by people under 22 years old. With the ECG app, Apple Watch is capable of generating an ECG similar to a single-lead electrocardiogram.
