This app has a timer you start at the beginning of your roast. When you hit the “first crack” button when first crack starts, the roast development time (RDT) percentage starts and the times to stop the roast for 16%, 18%, 20%, 22%, 24%, and 26% show up. You can also calculate the percent weight loss by entering the beginning weight and end weight.
