Store description excerpt
Track every bake. Master your sourdough. Levain Log is the bulk fermentation timer and bake journal built for home bakers who want to understand their dough — not just time it. Most sourdough failures come down to two things: inconsistent bulk fermentation and no record of what worked before. Levain Log solves both. INTELLIGENT Q10 FERMENTATION TIMING Levain Log uses Q10 — the biological principle that fermentation rate changes predictably with dough temperature — to give you accurate, real-time bulk fermentation estimates at every stage of the process. From your initial mix to your final stretch and fold, simply enter your dough temperature and Levain Log tells you exactly where you are in bulk fermentation. No more guessing. No more overfermented dough. STRETCH & FOLD LOGGING Log every stretch and fold with timestamps and dough temperature readings. Build a complete picture of your bulk fermentation from start to finish — and review it bake after bake to understand exactly how your dough behaves in your kitchen at any temperature. PROOFING TIMERS Set and track multiple proofing timers with notifications that alert you when your dough is ready — even hours later when your phone is locked and the app is closed. No more overproofed loaves because you lost track of time. HYDRATION CALCULATOR Calculate your dough hydration instantly. Dial in your formula and track it alongside your fermentation data for a complete picture of every bake. BAKE JOURNAL - PREMIUM Your complete bake journal lives in Levain Log. Review every bake with photos, ratings, and full fermentation data including temperature readings at every stage.

UNLIMITED RECIPES - PREMIUM Store unlimited recipes with full fermentation profiles. Compare bakes across different recipes and track your improvement over time.
