About Roast Master: Coffee Journal
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.
SEE YOUR ROASTING DATA
Every roast, captured and visualized:
• Full temperature curves — Bean Temp, Environmental Temp, and Rate of Rise
• Key events — charge, first crack, drop — with development time (DTR)
• SCA-style cupping scores: aroma, flavor, acidity, body, balance, sweetness, and more
• Agtron roast color readings
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.
FREE & PREMIUM
• Free: roast logging, curves, cupping, dashboard, and PDF export
• Premium: a generous allowance of AI Coaching sessions
Export any roast to PDF, free. No ads.
