I was using myfitnesspal for some time, but wanted to better track vitamins and minerals. Cronometer sure does track a lot of nutrients, but the first 2 foods I entered a search for didnt show, I would have had to add everything manually (60 nutrients). The biggest pitfall is no scanning ability, those 2 same foods scanned straight into myfitnesspal. I cant believe these guys charge money and you have to enter your foods...
