I got tired of always reworking the formulas or running into the house and plugging them into a spreadsheet so I worked up a quick iPhone web app to do simple ABV/ABW calculation from gravity or brix measurements.
I'm looking for feedback, comments and suggestions. Are my formulas correct? If it is useful maybe I'll expand it to some more calculations. Please let me know!
