Sourdough Calculator & Journal

Bread calculator and sourdough calculator in one app. Baker's percentage calculator, dough hydration calculator, sourdough starter tracker, bake timeline planner, recipe scaler, and a photo journal of every loaf — all offline, all in BreadMath. BAKER'S PERCENTAGE CALCULATOR Enter any flour, water, salt, and starter or yeast amounts. BreadMath shows live baker's percentages for every ingredient. Add multiple flour types — bread flour, whole wheat, rye, spelt, 00 flour — in a single recipe. Salt percentage and hydration update instantly. Save any calculation as a recipe in one tap. DOUGH HYDRATION CALCULATOR The fastest way to find your bread's hydration. Enter flour, water, and starter (with starter hydration) — BreadMath does the maths. Target hydration ranges shown for every common bread style: sandwich loaf, country boule, ciabatta, focaccia, baguette, bagels. Includes water from your starter so the number is correct. SOURDOUGH STARTER MANAGER Track your starter's health status and feeding ratio. Tap the build calculator to find exactly how much starter to feed for any recipe. One-tap "I just fed it" log with ratio (1:1:1, 1:2:2, 1:3:3, 1:5:5) and the next-feeding time. Full feeding history at a glance. FEEDING SCHEDULE & REMINDERS Never forget your starter again. Reliable notifications for every feeding interval — every 4, 6, 8, 12, or 24 hours. Pause when the starter goes in the fridge, resume when it comes back out. The dashboard shows the next feeding countdown so you can plan around it. BAKE TIMELINE PLANNER Plan a sourdough bake forwards from now or backwards from a target finish time. Autolyse, mix, bulk ferment, pre-shape, final shape, cold proof, bake — every step with its own timer. One-tap "start next step" advances through the bake automatically. Perfect for fitting a 24-hour cold proof around your day. RECIPE SCALER Halve, double, or scale any recipe to a target dough weight or number of loaves. Maintains every baker's percentage exactly. 16 BUILT-IN RECIPES WITH REAL PHOTOS Basic Sourdough, Whole Wheat Sourdough, Country Rye, Sourdough Baguette, Ciabatta, Focaccia, Multigrain, Soft Sandwich Bread, Honey Whole Wheat, Brioche, Sesame Bagels, Soft Pretzels, Neapolitan Pizza, Naan, Flour Tortillas, Cinnamon Rolls.

PHOTO BAKE JOURNAL Log every loaf with photos, stars, notes, recipe link, and tags. Use the presets or add custom tags. Edit any bake later — you're not locked in. Sort by newest, oldest, or top-rated. Forgot a photo? The journal uses the linked recipe's image so the entry still looks great.
