iPhone lovers know how exceptional the features on the device are, but apparently there is a life-saving app that can provide help in the event you are in an emergency.

A public hospital employee named Julia Thompson posted on Facebook about an iPhone feature that could potentially help save your life during an emergency situation.

At the beginning of the post she notes, “Many patients come in and we have had no way of knowing who they are or how to contact their next of kin. And their phones are locked!”

What many people are not aware of is that they can set up readily available medical information through their phones even when it’s locked, making it much easier for emergency responders to help out in a crisis situation.

The iPhone comes with a free app, simply called Health. The icon is a white box with a tiny pink heart in the top-right corner. Once you open the Health app, a menu bar appears at the bottom of the screen. At the far-right of the menu bar, there is a Medical ID icon that you tap to enter any necessary emergency information.

Once on the Medical ID screen, you can fill in categories such any medical conditions, blood type, allergies and reactions, and medications—just about anything that might help an emergency responder treat you in an urgent situation.

This can be a real lifesaver!
