How can I support / follow the health of a relative / friend with Elfie?

If you wish to help a friend/relative to monitor their health and earn a few coins, you can use the family support feature. Go to the Elfie app home page. In the Highlight section (below your plan), click on the "Family support" card. You can also find the family support invitation link in the Health page of Elfie at the top, alongside "My Health"
