Medical ID categories
One of the most useful features you can find in your iPhone is Medical ID categories. To access these, simply go to the bottom left corner when you want to dial in a number. Putting in crucial information relating to a specific contact can come in handy during emergencies.
For instance, you can input the contact’s partner, kin, parents, blood type, height, and weight. There’s also an allergies category if you know what that person is allergic to. Hopefully, you’ll never need to use this information at all, but it doesn’t hurt to be prepared for the absolute worst. Just make sure you input the correct data.
