Sourdough Calculator & Journal

Sourdough Calculator & Journal is a compact baking utility that takes the guesswork out of bread-making by handling hydration, baker's percentages, starter feedings, recipe scaling, and scheduling in one place. The app combines calculators for dough hydration and ingredient percentages with a starter manager, feeding reminders, a bake timeline planner and a photo journal so home bakers can reproduce great results reliably. If you want consistent dough feel, accurate scaling for multiple loaves, and a clear timetable for long cold proofs or same-day bakes, this tool keeps everything local and fast on phone or tablet without requiring an account.

Key Features

⭐ Live baker's percentage calculator that updates instantly when you add flours, water, salt, and starter or yeast.

⭐ Fast dough hydration tool that factors starter hydration and shows target ranges for breads like ciabatta, baguette, focaccia and sandwich loaves.

⭐ Starter manager with feeding ratios, ambient temperature tracking, one-tap 'I just fed it' logging and next-feeding countdown.

⭐ Bake timeline planner to map autolyse, bulk ferment, shaping, cold proof and bake steps forwards or backwards from a target finish time.

⭐ Photo bake journal plus recipe scaler and built-in recipes; Sourdough Calculator & Journal saves photos, notes and tags for every loaf.

Advantages

✅ Accurate calculations: baker's percentages, hydration and starter-build math are handled automatically so you can focus on technique.

✅ Offline-first privacy: all recipes, photos and calculations live on your device with no account or tracking required.

✅ Practical scheduling: local notifications, step timers and a clear dashboard make it easy to fit multi-day bakes into a busy week.

✅ Flexible scaling and layouts: scale recipes to dough weight or number of loaves and use tablet-friendly views for larger kitchens; Sourdough Calculator & Journal supports metric and imperial units.

Disadvantages

❎ Some advanced features—full journal, unlimited photos, bake planner, notifications and the complete 16-recipe library—require a one-time BreadMath Pro purchase (listed in-app).

❎ No cloud sync or account system, so entries and photos stay local and won't automatically transfer between devices unless you export them yourself.
