What’s New in iOS 8

iOS 8 vs iOS 7 Lock Screen

There is one nice change to the iOS 8 lock screen. Apple now includes a Medical ID that lists an emergency contact, medical conditions, notes, medications and other important information without the need to unlock the phone. 

You access this information in the iOS 8 Health app, and can update easily. This is a very nice feature and better than using an ICE contact if you lock your iPhone.
