As an ultralight backpacker, I was always using my calculator to figure out the calories per ounce of certain items I was buying in stores. Now with this app I have simplified the process of getting the information I need with fewer errors.

Simply input the grams and calories of a serving from the nutrition label and press "calculate" and voila! Your cal/oz calculation is complete.
