As much as folks in the software world believe in complete software development freedom, you can't just build whatever you want and release it. Laws exist that regulate what you can release as much as folks might dislike it. Health apps are just one example.

The problem is that OP literally mentions "medical caregiver" as distinct from "families" which can be interpreted to mean someone that operates as covered entity. That alone puts OP under the risk of being sued and being punished with a very large fine. All a user needs to do is put their data there, share the info with their care assistant who works for a health company. Once that happens, OP is breaking the law.
