I've never asked a first responder if they're aware of this feature--I hope they are. I assume something similar is available on Android phones.
we had paramedics come to one of our club meetings, they made it clear that they are NOT going to be checking phones or calling services like RoadID. They said the most useful info for them is date of birth, any medical conditions, allergies, and medications. We had cards made up for members to fill in this info along with their names and emergency contact name and number. We printed one of the common medical logos on the other side so it would be hopefully be noticed by a first responder.
