I love this app. Today when I went to the store I used it to check to see what nourshment serveral foods will give me. I had a couple of other tools but they failed to give me as much information as Cronometer provides. I also like the fact that I can write things in a notebook and then go to my computer where it is easier to see what I am doing. Look forward to seeing how others are using the app. Oh, I also discovered that I needed to make some changes in what I was eating in order to get some nutrients I was not getting. Magnesium (sp) was one of them. I also discovered that I was taking a lot more b12 that my body should require. I had not read the labels on my vitamins and discovered I was paying for B12 tabs when my mens vitaming was already supplying it to me.
