The Little Calorie is to help you maintain or lose weight. It can even be used to gain weight if that is your goal. The Little Calorie has functions for logging the number of calories you eat. It can also calculate the amount of calories (or fat) you lose by training and/or eating a balanced diet. A new feature for this release is the "Diet Diary Notes". Here you can write your own daily diary comments, such as the food you ate during the day.
