Great Potential! This app shows great potential but lacks some major features. Design-wise: - option for portrait or landscape use - large touch friendly buttons for use during roasting - better thought overall layout and navigation. Plotting a profile during roasting should allow for record of more events other than 1st crack, start and end. You could introduce: - coffee drop (in case of preheating) - 2nd crack start and end (not necessary for roast completion) - Event logs (description user customizable). All the best!
Cool app I couldn't get it to work on my Dietrich IR please post a tutorial.
