Enjoy health and fitness data through apps and devices * * *:

You can authorize other apps and Health to enjoy health and fitness data. For example, a fitness training App is installed, and its exercise data can be displayed in "Health". Fitness training applications can also read and use data enjoyed by other devices and applications (such as your heart rate and weight). If you didn't authorize the App and health sharing data when setting up the App, you can authorize it later, or you can remove the permissions of the App.

In the health App, you can view health and fitness information. For example, you can check whether your symptoms have improved over time, and check the results of fitness records, sleep, mindfulness and other projects.
