Sync data between Apple Health and Sahha
The Apple Health app provides a central and secure place for your health and fitness information, so it’s easily accessible and under your control.
Health automatically counts your steps, walking, and running distances. And, if you have an Apple Watch, it automatically tracks your Activity data. You can also enter information into a Health category or get data from any of your favorite apps or devices that are compatible with Health.
On your iPhone or iPad, open the Health app.
If you're on your iPhone, tap the Summary tab, then tap your profile picture in the upper-right corner. If you're on your iPad, tap Profile in the upper-left corner.
Tap Health Details, then tap Edit.
Add your information, like your date of birth and blood type.
Tap Done.
On your iPhone, you can also set up your Medical ID or register to be an organ donor from your profile.
