Great product, ok app

It would be hard to review the app without mentioning the product, so I’ll start by saying the product itself (we have the bracelets) is awesome! What a great idea! Due to a severe nickel allergy, I have a hard time wearing standard medical ID bracelets, so this fabric one rocks. If they can get the word out to EMS around the country (my husband is working on it here in Albuquerque), even better.

Now the app.... It’s not a bad app, but instructions would be nice. It’s taken a bit to figure out how to do some things in it, and there is no resource for when you get stuck. Also, the space for medical information is TINY! I have several medical conditions, and I had a very difficult time fitting my conditions and meds into such a small space. The other complaint I have is that the family notification doesn’t work. I scanned my son’s bracelet, and my husband and I each received the notification that it had been scanned. Tapping on the notification, however, didn’t do anything except make it disappear. Even going into the app didn’t result in further info.

If these issues could be fixed, this would be an outstanding app!
