Of the many new additions to iOS 8.0, the Health app had a lot of limelight focused on it. While we haven’t yet seen it in its entirety (functionally), t1he app is a very promising candidate for a complete health-related integration within iOS.
The Health app also comes with a feature called Emergency Medical ID. The Medical ID section lets you store all your important medical information so that it’s available in a one-tap access. You will have to setup the Emergency Medical ID in iOS 8.x so that it’s accessible for yourself and others when the need arises.
