## What is 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. Start from autolyse, mix, bulk ferment, pre-shape, final shape, cold proof and bake, then make the plan your own: rename steps, change their times, add your own, delete them or drag to reorder. Every step has its own timer, and one tap starts the next step. Your plan and a running timer stay saved when you leave the screen, and BreadMath alerts you when a step's time is up, even with your phone locked. 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. Every recipe has a full ingredient table with baker's percentages, scaled to 500 g flour, plus step-by-step instructions with times and temperatures.

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.

WORKS OFFLINE — NO ACCOUNT
Every calculation, recipe, and photo lives on your device. No sign-up, no cloud, no account. The whole app loads instantly.
