The Diet Tracker Food Scanner will help you keep track of your diet and also enable you to read nutrition facts by just scanning the barcode. It is a multiuser application so it can be used by multiple people on the same device. So the whole family can keep track of their diets. This app will calculate points based on the nutritional content. The calculated points should be the same as Weight Watchers PointsPlus points. So if you have a Weight Watchers account you could use this program to keep track of your points offline but you also have ability to access Weight Watchers from the application by using WW button. This program will keep track of the nutrition value in the food you are eating and the calories as well.
