There are plenty of iPhone features that feel like you just can’t live without them. But there is one that can literally save your life: Medical ID.
If you get into an accident or otherwise become unconscious or unresponsive, a first responder can pick up your phone and place an emergency call. But they can also tap the Medical ID button to be taken to a screen that shows important information about you: Age, blood type, allergies, medical conditions...whatever information you wish to share that may help a medical professional to treat you properly.
Setting it up is a snap, but you may not have thought about it because you access it through the Health app rather than Settings.
