There's bunches of them, some free some not. I tried one and while hate is too strong a word, I did not like it. It was so un-useful and unmemorable I don't even remember which one it was. It wasn't convenient, so I found a little program that runs on my Palm. It works better for me because it's on hand when I'm near temptation (I can check out just HOW badly it would put my diet off for the day) and can enter stuff as I consume, else I'll forget and then what good is it?

Admittedly, I haven't even been using that recently and have gained more than a couple pounds as I've indulged in stress- and depression-eating habits.
