RoastEar

First crack can be hard to hear over a fan. RoastEar gives home coffee roasters a focused timer, large milestone controls, and optional acoustic assistance that listens alongside you. YOU STAY IN CONTROL Mark charge, dry end, first crack, second crack, drop, and cool by hand. When acoustic assistance is enabled, RoastEar analyzes microphone input on your device and may suggest first- or second-crack timing. Confirm or correct every suggestion. The timer and manual controls work without microphone access or a subscription. BUILT FOR THE ROAST β€’ A large clock and controls designed for quick glances β€’ Session-specific noise calibration and adjustable sensitivity β€’ Live crack-rate context rather than a generic loudness meter β€’ Development time and development ratio β€’ Manual bean-temperature logging with temperature curves and rate of rise β€’ Weight loss, ratings, roast notes, and cupping notes β€’ Import an Artisan roast free. Pro unlocks unlimited roast history and export. β€’ Optional retained audio for your own review PRIVATE BY DESIGN Audio analysis runs on your device. RoastEar does not serve ads or track users across unrelated apps, and no RoastEar account is required. RevenueCat receives pseudonymous Apple purchase and entitlement metadata for Pro access, restoration, and subscription analytics; no roast or audio data is sent to it. A separate legal-record service retains your legal choice and receipt, document versions, and pseudonymous installation identityβ€”not your roast or audio content. Optional retained audio stays only on the originating device, is excluded from device backups, and leaves only when you explicitly share it. Roast records use your private iCloud database when iCloud is available. ROASTEAR PRO Import an Artisan roast free. Pro unlocks unlimited roast history and export. The free version also includes the manual timer, calculators, and one saved roast. Acoustic results depend on the roaster, batch, device placement, microphone, and surrounding noise. RoastEar is a logging companion, not a safety monitor. Never leave a roaster unattended.
