If, like most savvy users, you lock your iPhone when it's not in use, you’d surely find yourself in quite a bind should a bad (*) or really bad (**) situation materialize.
* = you misplace your iPhone, a Good Samaritan finds it but can't return it because she doesn't know to whom it belongs
** = you’re unconscious after an accident and an EMT responder needs to know if you suffer from any pressing medical conditions
Because it simply and effectively solves these two problems, we love Close Call, a free app that layers your iPhone’s wallpaper with your emergency contact information and a life-saving message (like "I'm allergic to penicillin").
The vital information can then be placed, in the form of a red banner, onto any image in your photo library. Once saved, it will then appear as your wallpaper.
