I do hear what you're saying, and I've wrestled with "not everything should / can be an app". That being said, I'm still trying to solve food (for myself) with computers, haha.

Right now, that looks like trying to create a nutritionally-optimal "dog food for humans", using combinatorial optimization solvers. I think I'm going to write something up as a post when it becomes a bit more feature-complete.

It's living at chow.seanjohnsen.com if you're curious! Would love feedback from someone who has thought along these lines.
