Besides not being very intuitive to set up, which was annoying, and having to upgrade to add more than one contact, also annoying--and I never did figure out how to get back to the screen where you enter information about yourself to modify it--it turned out that if you have ANY KIND OF NOTIFICATION ON YOUR IPHONE, the information you entered is blurred and unreadable, and Apple wont allow a workaround. So they offer to send you cards to keep on your person and in your car!!!! The whole point of getting this app is thus rendered moot. I am very annoyed. Why not just SAY "Will almost certainly not work with iPhones if you engage in any social media." ???
What a pointless waste.
