## What is Roast Master?

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.

## Version history (last 4 releases)

### 1.3.0 — 2026-09-04

Your dashboard now opens from your first roast.

DASHBOARD
Each section unlocks as soon as it has the data it needs, instead of keeping everything locked until 3 completed roasts. Sections that are still locked show what they need and how much further you have to go.

FIXES
• Deleting Agtron readings errors
• Reminders are recalculated from the roast date, not from today
• Roasts you have already cupped show as done in the reminder list

IMPROVEMENTS
• The RoR axis on roast curves picks its own scale, so steep and gentle roasts both read clearly
• Saving an Agtron measurement confirms the save and tells you how your degassing reminder time changed

### 1.2.0 — 2026-08-31

• Agtron color measurement screen — improved layout and full Korean localization
• Introduced usage analytics to help us improve the service
• Stability improvements and bug fixes

### 1.1.0 — 2026-08-20

• Login now opens inside the app and returns faster.
• Strengthened login security.

### 1.0 — 2026-07-05
