The right side of the screen (+) is all I'm using right now and still don't know everything about the app.

But food for thought wouldn't it be easier to take a picture of your meal and then have little icons "Protein" (grams, Oz, handful size/ estimate, etc), "Sugar" (grams and it's OK to leave blank if there's no label), "calories", "veggies", "ProteinType", so on and so on... I really like the quick take a picture and look back on my food chooses with a visual but I really wish there was a system that allows you to check off what it is... rather then a comment box that doesn't integrate with the apps features... Still great app though
