Can I sync my garmin vivo smart 4 with apple health in iOS 15

Hi jridberg,

Thanks for coming to Apple Support Communities for help getting your Garmin watch data into the iOS Health app.

You'll be doing this through the installed Garmin app on your iPhone. Have a look here: Manage Health data on your iPhone, iPod touch, or Apple Watch and see the section "Add information from other apps".

Garmin also has a resource on their support site: What Garmin Connect Information Can Be Shared With Apple Health?

Have a fantastic day!
