Crust Log vs Sourdough Tracker

Build a Better Loaf Crust Log is the sourdough companion app designed for bakers who care about the craft. Track hydration percentages, manage feeding schedules, log every bake, and use the reverse bake timer to plan your way to a perfect loaf. STARTER MANAGEMENT Create and track your sourdough starters with detailed feeding logs. Record flour type, hydration ratio, water and flour amounts, and temperature for every feeding. Set reminders so you never miss a feed. Monitor your starter's age and activity status at a glance. RECIPE LIBRARY Build your personal recipe collection with precise ingredient weights, hydration percentages calculated automatically, step-by-step instructions, and baker's notes. Organize by category — sourdough, focaccia, pizza, bagels, and more. See every loaf you've baked from each recipe in one place. BAKE LOG Record every detail of every bake: bulk fermentation time, proof duration, oven temperature, bake time, and a 1–5 star rating. Capture photos of your loaves. Write tasting notes on scoring, crumb, and crust. Over time, spot the patterns that separate a good bake from a great one. HYDRATION CALCULATOR Instantly calculate your true dough hydration — accounting for the flour and water in your starter. Input your dough flour, water, starter weight, and starter hydration to get an accurate total. Always free, always available. REVERSE BAKE TIMER The feature that changes how you plan a bake. Set the time you want your bread finished, and Crust Log works backward to schedule every step — mix, bulk fermentation, shaping, preheat, bake, and cool down. Customize durations for your recipe and get reminders before each phase so nothing slips. LOAF COMPARISON Compare two bakes side by side. See photos, ratings, fermentation times, oven temps, and bake durations together to understand what worked and what to adjust next time.
