I think this is a really neat idea, but I'm a little concerned about how they store data.
>My health data is secure and private. Health Wizz does not share my data with anyone. Period.
I get the feeling that I would interpret that claim differently than how they mean it. I would expect that to mean that they either don't store my info on their servers, or they e2e encrypt it such that only I (or anyone to whom I give some access permissions) can access it. I.e., I would expect that Health Wizz employees cannot access my health data, unless I specifically allow them to.
But I'm sure that's not the case. At the very least it's not provably the case that they can't access it - their word is really the only assurance.
Bottom line, if they're storing my data in an unencrypted form, or in an encrypted form where they have the means to decrypt it, I'm a hack away from having very personal details exposed.
