Awesome!
You only need this app to setup your recording. Get to the point of your message since you only have a minute to record. Short and sweet. Basically, I recommend recording things that could save your life.
I recorded my name, DOB, allergies, emergency contact.
Only thing I would recommend for the app is to be able to type of in your emergency details. I'm just thinking of a scenario of what if they can't hear/understand what you recorded.
So far, I would recommend it.
I haven't tried it in real life and I'm hoping it doesn't get there.
