The Link App is the accompanying mobile application for the Link Sample Roaster by Nucleus Coffee Tools and Kaffelogic. Utilising this app, Link users can input a range of information about the coffee they wish to roast, and the app’s algorithmic profile selection will provide the most ideal recommendation for roast Profile Pack, Power Curve/Roast Profile, Suggested Development Range, Fan Action (fan speed), and the Expected First Crack for each coffee. The Link App also has several features to accommodate different coffee roasting scenarios, including Altitude Calibration, Arabica Advanced to input the screen size of coffees, All Species Mode for non-Arabica coffees, Advanced Roast Details for roast batch size, and Heirloom Cupping for landrace varieties.
