Your home coffee lab. Track beans, log brews with precision, and dial in the perfect cup.
Roast is the coffee journal built for home baristas who care about every cup.
Track your bean collection, log every brew with precise recipes, and use data to dial in the perfect cup. Whether you're pulling espresso shots or perfecting your V60 pourover, Roast captures every variable so you can reproduce your best brews and systematically improve.
TRACK YOUR BEAN COLLECTION
Add every bag with origin, roaster, roast date, process, and your own tasting notes. Mark beans as open, sealed, or finished. Know exactly what's on your shelf and how fresh it is.
LOG EVERY BREW WITH PRECISION
Record dose, water weight, grind size, water temperature, and brew time. Add tasting notes with structured sliders for acidity, sweetness, body, and bitterness. Rate every cup 1-5 stars.
BUILT-IN BREW TIMER
Lap timer with bloom and pour markers. Start brewing, tap lap at each pour, stop when done. Brew time auto-fills your log. Never lose track of your recipe again.
BREWING STATS AND TRENDS
See your brewing streaks, favorite methods, top-rated beans, origin breakdown, and brews per week. Understand your habits and see how your coffee game improves over time.
DIAL-IN MODE (PRO)
Compare all your brews of a single bean side by side. See exactly which variables - grind, temp, ratio, time - correlated with your best cups. Dial in faster with data.
AI BREW ASSISTANT (PRO)
Ask Grok anything about your coffee, backed by your own brew history. "Why does my V60 taste sour?" "Which of my beans should I brew today?" "What should I try next?" Your personal coffee coach with real context.
