This is great and I have seen some apps similar to it. One of the things I believe would be a hard problem to solve is, how does a mere picture depict the exact calories? For example, a pasta or a soup can be loaded with butter versus made without it. This is usually not visible with the pictures.

Maybe one of the ways is to identify with the shine and the image differences since fat floats on top. But then how do we add a quantitative metric to it as in how many tbsp of butter were used?
