The idea has merit. Aside from the demo itself, I'm more interested in the business opportunity.

You could partner with grocery stores. The user would have an account, not tied to any one particular grocer. It would track all of your grocery purchases, and like your demo, give you nutrient insights as well as recipes and maybe coupons and money-saving tips. Lots of stuff you could do with that.

There's a company already pursuing this (disclosure: my current employer built their site/app for them), but it starts with the diet definition and then creates shopping lists, with callout links to online grocers.

I was also thinking about monetization, but was more thinking of a SaaS for consumers. Do you happen to know the grocery industry to know more about their interests for the app? I mainly see it as a way for them to place ads in the app
