I have it, and to be honest it isn't worth it. It has very limited food lists to pick from when you do your food journal and it doesn't really take health into account. for instance, if I ate 3 ice cream drumsticks, chicken wings and beer, and pizza and input that, it would tell me i was balanced for the day because it goes by the calories and not nutritional value. It was a good idea for a DS application, just really poorly done. you're better off trying an online application like fitday.com or something like that.
