What it is
Somebody in every family ends up trying to remember who had what and at what age, usually the week before an appointment. Relative Health gives you one place to put all of it, across two or three generations, and turns it into a document your doctor can read and act on in the time you have with them. Because it holds health information about relatives who never signed up for anything, it is encrypted on your phone with a key nobody else can see.
The hard part
Family health history is about as private as information gets, so the app is built so that we cannot read it either. It is encrypted on your phone, with a key that never leaves it. If somebody broke into the server tomorrow, there would be nothing there worth taking.
