The free ICE App is one that everyone should have — and hopefully no one will need to use. The idea is simple: everyone is supposed to have an ICE contact in their phone, "ICE" standing for "in case of emergency." ICE App suggests that you put its icon in the upper right-hand corner of the main screen. The app lets you enter four categories of info: who you are, your emergency contacts, medical info, and allergies.

Does it worked when locked?
Thanks for the review, Jim! Does this app work when the iPhone is locked? I keep my devices locked because they remember my passwords, but that means this kind of information is only available to me, which makes it useless. I found an ICE app for my Android phone that replaces the default lock screen so that emergency info is accessible (and the numbers are dialable) without unlocking the phone. This iPhone app looks very similar, but I can't find any evidence that it's accessible from the lock screen.
You're right. It doesn't seem
You're right. It doesn't seem to be set up to work when the screen is locked.
