Please pardon the quality; I definitely made this in Word & MS Paint and am not a graphic designer by any means.
It somehow got cut off, but if you have an older version of Android, the app has its own lock screen mode you can use.
A lot of people were saying they'd never heard of this so I wanted people to be aware of it. This way if you are every hurt or incapacitated and someone is trying to help you, they can call your emergency contacts. Also helpful if you have important allergies or require important medications and can't tell someone.
edit: also, here is the link to the ICE app for Android: https://play.google.com/store/apps/details?id=com.appventive.ice
I really like this one!
Here is a list of things you can do (copy/paste from the page)
You can use the app even when the phone is locked as you can add it to the lock screen. I also like that there is the option for "If found" information at the bottom of the screen.
For Android users, I myself have this app:
https://play.google.com/store/apps/details?id=com.appventive.ice
You can find your own under I.C.E. Or in case of emergency.
For your peace of mind, android has something like this.
I'm sure the Apple store has something similar.
I thought most ICE apps have a setting for the lockscreen. For instance: https://play.google.com/store/apps/details?id=com.appventive.ice
