Track your vitals on Apple Watch
In the Vitals app, you can view overnight health metrics—heart rate, respiratory rate, wrist temperature, blood oxygen*, and sleep duration—to get a better understanding of your daily health status. On Apple Watch Series 12 and Apple Watch Ultra 4, you see heart rate variability instead of sleep duration, and you also see metrics collected during the day—heart rate and heart rate variability.
The Vitals app establishes a typical range for each of your health metrics collected as you sleep and during the day. If multiple metrics are outside your typical range, you receive a notification along with context for factors that may be involved—like medications, elevation changes, or illness, for example.
Note: Your Apple Watch is not a medical device. For important information about using the Vitals app safely, see Important safety information for Apple Watch. For models of Apple Watch purchased in the United States on or after January 18, 2024 with part numbers ending in LW/A or LS/A, Blood Oxygen is not available in the Vitals app. Learn how to identify your Apple Watch.

Note: The back of your Apple Watch needs skin contact for features like wrist detection, haptic notifications, blood oxygen level measurements, and the heart rate sensor. Wearing your Apple Watch with the right fit—not too tight, not too loose, and with room for your skin to breathe—keeps you comfortable and lets the sensors do their job. For more information, see the Apple Support article Wearing your Apple Watch.
