Fermentation is all about timing — and your sourdough starter won't remind you when it's hungry. FermentBuddy is the kitchen companion that remembers what you forget, so you never kill another starter or over-ferment your kombucha again. TRACK ALL YOUR FERMENTS IN ONE PLACE Whether you're nurturing a sourdough starter, brewing kombucha, culturing kefir, or making sauerkraut, FermentBuddy keeps every project organized with timers, notes, and photo logs. Support for 13 fermentation types including kimchi, miso, tempeh, yogurt, jun, vinegar, water kefir, and pickles. SMART TIMERS THAT ACTUALLY HELP Set recurring feeding reminders for your sourdough starter. Get notified when your kombucha first ferment is ready. FermentBuddy sends push notifications so you can stop setting random phone alarms and sticky notes. Pro users get temperature-adjusted timers that use fermentation science to adapt timing to your kitchen conditions. GUIDED WORKFLOWS FOR EVERY STAGE New to fermentation? Follow step-by-step timelines that walk you through each stage — from mixing your first sourdough starter to bottling your kombucha. Visual progress tracking shows exactly where you are and what comes next. TROUBLESHOOTING THAT ACTUALLY WORKS Mold on your sauerkraut? Starter not rising? Kombucha too vinegary? FermentBuddy's diagnostic system helps you identify problems with 34+ symptoms, causes, severity levels, and actionable solutions. No more frantic googling — get answers in seconds. DOCUMENT YOUR PROGRESS Log each batch with ingredients, dates, notes, and photos. Track what works and what doesn't. Build your personal fermentation recipe book over time. Export your history as CSV or PDF to share or save. HOME SCREEN WIDGETS Check on your active ferments without opening the app. Small, medium, and large iOS widgets show your running timers and next actions at a glance. BEAUTIFUL, WARM DESIGN FermentBuddy's "Artisan Pantry" design feels like a cozy kitchen companion, not a clinical spreadsheet. Warm terracotta and olive tones, organic typography, and signature rising bubble animations bring your ferments to life. Full dark mode support with warm undertones for late-night feeding sessions. WORKS OFFLINE Start tracking immediately — no account required. FermentBuddy works offline with automatic cloud sync when you're connected. Your data is always safe and accessible across devices.
