Idea for an app that I don’t believe exists

I think there’s a niche for an app that you can give the password for to doctors, insurance providers, your bank, etc, that contains your personal details that you don’t want laid out on the desk of a nurse or on a piece of paper that’s laminated and held to an I.d card. I picture a password-protected app with a login at one point and then at least one further login within to access specific details. <br><br>For instance, for doctors, you could have a login for personal history that knows what medication and dosages you’re on, and also allergies and stuff. <br><br>A second login within the same app could be for your insurance providers, and could list which of their programs you have and have had.<br><br>A third could be for your bank, and list your current accounts, loans, etc.<br><br>I like this concept because I don’t like the idea of that information sitting on paper, but I also don’t want to have 100 different apps for all my different services, or to type all that information out anytime it’s needed (and open the app for each service to verify). <br><br>Has anybody seen an app like this? Do you think there’s a demand for it?
