Roast Master: Coffee Journal

Log every roast, then let your AI coach tell you exactly what to change next — temperature curve, events, cupping. Better coffee, batch after batch.

Roast Master puts your roasting data and an AI coach in one app. Log every roast, see it clearly, and get AI coaching on exactly what to change next — batch after batch.

AI ROASTING COACH Roast, log your curve, and AI analyzes it — your temperature curve, your events, your cupping — then gives you a focused, practical tip for your next batch. It's like having an experienced roaster review the roast with you and tell you exactly what to try next.

YOUR ROASTING DASHBOARD • Roast DNA: flavor radar, Agtron distribution, and DTR gauges • Cupping trends over time and batch comparisons • Activity heatmap to see your roasting rhythm at a glance

FOR ROASTERS WHO WANT TO IMPROVE Every batch becomes data you can review and compare — with AI helping you turn it into your next, better roast.
