The problem is that A. A photo has no depth information to tell you the actual size of something, B. A photo cannot tell you what is behind something else so you can't see what's hidden, and C. Most importantly, when you're done cooking, a lot of ingredients in a food are "invisible" such as milk, butter, sugar, etc. and no camera or fancy AI can tell you what was used to make a food.
There is no "no one has executed it well enough" here. Every single attempt at this app idea has these exact same limitations. This not the same as a bird or plant identification app.
So many people have tried this exact same app. Good job making something, but I'm trying to save you a lot of wasted effort.
