Beyond HIPAA and similar regulations, there's the broader challenge that part of the intended audience probably would not want to use it for the same reasons. Any health care professionals that handle information like this are subject to the same rules and would only use tools that comply to minimize liability.
And there's the related problem of those people probably already having a lot of tools that they use and prefer. Another tool adds to their work load.
But I don't want to completely discourage you. If you are serious about turning this into a business, I'd look into how to connect to other tools. Maybe add some IOT integrations to the mix, etc. Most GPs would love a good tool like that. Many of the tools in this space are more than a bit crap. The key to success is understanding who experiences the most pain here and taking that a way (which in this context is also a nice metaphor).
Some feedback:
- who or what is Kate? Not really clear what this name is about.
- what's the business model here? Who pays for what and why? How is that going to evolve.
- get a designer or level up your own design skills. I'm not one but I can see you didn't use one.
- work on your pitch, it raises a lot of questions. Like how you are storing information, what the pricing is, and how you deal with privacy issues, etc. Vaguely hinting at that being important in a hand wavy way doesn't make it better. Taking topics like that serious requires a more structured approach to address those things. This communicates the opposite of what you probably intend here.
