Also there should be a way to input what you actually it so it can self-adjust based on what you're actually doing rather than what you'd ideally be doing. As in "okay we can see that you don't really eat X so let's try Y". But I guess then you'd loose 95% of potential users cause that's a pain to do.
There was this mental health company that would suggest the right medication based on statistics. Supposedly it was much more accurate than regular diagnoses that you'd get from a doctor. I can't find it thought ;C
About adapting your profile, after now 40+ interviews it seems it would only work for really specific segment (like fitness addict) as it implies to much daily inputs.
One note that you have probably already thought of is make sure to have multiple options. In the working world, it seems to me that the hardest thing to do is find time for cooking good meals. So having a few options for quick, medium prep, and longer prep would be insanely helpful. Looking forward to it!
