Calculation App for Android

The calculator would be a simple interface that allows you too enter information into the calculator from off of a nutritional label. The fields would go something like entering the total carbohydrates per serving, the total amount of soluble fiber, the total amount of insoluble fiber, and the total amount of protein. The user would then hit a button saying "Calculate" which would then add the protein amount with the fiber amounts before subtracting that total from the carbohydrate amount and listing the actual carbohydrate amount.
