I use MyFitnessPal (http://www.myfitnesspal.com). There are many calorie counting apps out there… but this one will allow you to scan a barcode with your smartphone to track what you eat. Simple!
They have an app for iPhone, Android & iPad. If you sign up for the free service and free app, hit me up (http://www.myfitnesspal.com/shartzog) and I will share my daily calories.
What do you use? Happy counting.
