CAFESSIO Coffee Roaster Tool

CAFESSIO Coffee Roaster Tool is a roasting companion for home roasters, micro-roasteries and cafés that roast their own coffee. Start a roast in seconds, log what matters while the beans turn, and make your best roasts repeatable.

RECORD EVERY ROAST
• A live timer that stays accurate with the screen off, in the background, and even if the app is closed
• One-tap events: Charge, Yellow, First crack and Drop, with undo
• Fast temperature entry on a big keypad for BT and ET, with probe offsets
• Rate of Rise, development time and DTR as you roast
• Log gas, fan, drum and power changes
• Alerts before first crack and at your target drop, with optional spoken announcements
• Home-screen widget: start your ready recipe and follow the live timer

UNDERSTAND THE CURVE
• Roast graph with BT, ET, RoR, event markers and your recipe target
• Roast summary with phases, weight loss, DTR and actual vs. recipe
• A timeline you can edit after the roast
• Share a branded image of your roast curve

REPEAT WHAT WORKED
• Recipes with targets, a visual profile and version history
• Roast again with one tap
• Consistency view across batches of the same recipe
• A library of 50 popular roast profiles to start from

MANAGE YOUR COFFEE
• Green coffee inventory that deducts every batch automatically
• Your roasters: 100 common machines to pick from, or set up your own
• 12 calculators: weight loss, DTR, batch scaling, yield, green needed, roast cost, cost per kg, density and more
• Cupping sessions with blind codes

PRIVATE BY DESIGN
No account, no ads, no tracking. The app works fully offline and has no internet permission: your roasts stay on your phone.

FREE AND PRO
The free version includes the roast timer, events, graph, calculators, notes and every language, with up to 10 saved roasts, 3 recipes and 3 green coffees. Cafessio Pro is a one-time purchase that unlocks unlimited history, recipes and inventory, roast comparisons, consistency and advanced analytics, cupping, CSV and Artisan-format export, voice alerts, Pro tools (roast day planner, blend builder, development targeting, rest planner) and more. No subscription.

Temperatures are entered by hand; Bluetooth probe connections are not supported yet.

Recent changes:
• Correcting the drop temperature now replaces the reading instead of adding another point; affected roasts are cleaned up automatically, so curves and Artisan exports show the right value
• Pro purchase and restore no longer wait forever when Google Play doesn't respond
• The notification's Cancel button is now protected from other apps
