Losing weight involves behavior change, exercise, and diet, and this app takes the guesswork out of the latter. By far the most powerful nutrition aid we've found, this app tracks your calorie and nutrition intake, as well as your exercise, to help you gain control of your intake. Charts and graphs provide powerful motivation as they show how far you've come. It's also super-easy to use; just scan the bar code of packaged food or type the first few letters of a dish's name to search the app's 420,000-food database.
