ICE

ICE is designed to be a great help in case of emergency. The first helper is able to see who to call and which person he deals with in only a few clicks.

You can add ICE to your lockscreen with the WidgetLocker app.
There will be no own lockscreen implementation because of many different Android devices and versions.

ICE can translate your information to many different languages.
