Find the stock Health app and open it.
In the bottom right corner, you will see a little asterisk symbol that says Medical ID. Tap it.
Enter your info. Include things medical professionals would need to know if you were unable to communicate with them for some reason. Make sure lock-screen display is enabled!
Once your information is complete to your satisfaction, tap 'Done,' found in the top right corner.
To double-check that it worked, lock your phone and then swipe right. In the bottom left corner, select 'Emergency.'

This information is handy even if you don't have an iPhone, in case there's an emergency involving a friend, family member, or even a stranger who does own one! 😊
