Your ferments deserve better than sticky notes. Meet Fermenty: a thoughtfully designed fermentation tracker for home fermenters, from your first jar to your next great batch. Keep kombucha, sourdough, kimchi, yogurt, beer, wine, mead, pickles, and hot sauce organized in one place. TRACK YOUR WAY Choose a popular ferment type or create your own. Record salt percentages, start a batch now or schedule it for later, and plan multiple stages with target durations. Pause, resume, or duplicate a batch whenever you need to. TIMERS AT A GLANCE Follow batch progress with live timers. Live Activities bring your timer to the Lock Screen and Dynamic Island on supported devices. CAPTURE EVERY DETAIL • Log temperature in °C or °F and track pH readings. • Spot changes over time with temperature and pH charts. • Add photos, observations, and batch notes. • Record tasting notes and rate results from 1 to 10. • See readings, photos, notes, and stage changes together on a chronological timeline. REMINDERS THAT FIT YOUR ROUTINE Set recurring check-ins daily, every few days, or weekly. Add advance alerts before a stage is due to finish. THREE HANDY CALCULATORS • Brine: calculate salt amounts and brine concentration. • ABV: estimate alcohol by volume from original and final gravity readings. • Baker's Math: work out hydration, water amounts, and ingredient weights using baker's percentages.
