You nailed a roast. The beans smelled incredible, the cup was balanced, everyone wanted more โ and six weeks later you have no idea what you actually did. Kaava closes that loop. ROAST TIMER Time every session with an event-driven timer. Log First Crack, Second Crack, and Drop in real time with temperature and weight at each event. Every second of the roast is captured automatically. ROAST JOURNAL Every session is saved the moment it ends: duration, temperatures, weight loss, notes, and photos. Scroll back through months of roasts and find the one you want to repeat โ then repeat it exactly. BEAN PANTRY Track your green coffee inventory by origin, supplier, processing method, and altitude. Always know what you have, where it came from, and which roasts used it. CUPPING RECORDS Capture structured tasting notes with an interactive 9-axis flavor wheel: Fruity, Floral, Sweet, Sour, Roasted, Nutty, Spice, Vegetal, Body. Link each cupping directly to the roast that produced it. EQUIPMENT Organize multiple roasting machines and brew devices. Switch between them in one tap at the start of each session. SHARE YOUR BEST WORK Every roast and cupping session generates a shareable card โ your timer events, flavor profile, and photos in a single image. Share to Instagram, WhatsApp, or anywhere else. Everything is stored on your device. No account. No subscription. No cloud required. Your records are yours. Free to download and use.
