Hi DCRendi,
Thanks for coming to Apple Support Communities for help today.
This article can help you share data with a person or an app: Share your data in Health on iPhone
"Share health and fitness data with apps and devices
You can give other apps permission to share health and fitness data with Health. For example, if you install a workout app, its exercise data can appear in Health. The workout app can also read and make use of data (such as your heart rate and weight) shared by other devices and apps. If you didn’t give an app permission to share data with Health when you set up the app, you can give permission later. You can also remove permission from an app.
To share your records from healthcare providers with apps, see Share your health records with other apps.
- Tap your picture or initials at the top right.
- If you don’t see your picture or initials, tap Summary or Browse at the bottom of the screen, then scroll to the top of the screen.
- Below Privacy, tap Apps or Devices.
