Sourdough Calculator & Journal is a baker-focused utility that handles the numbers and timing behind sourdough baking so you can focus on shaping and baking. The app calculates baker's percentages, dough hydration (including water from your starter), scales recipes, plans bake timelines, manages starter feedings and keeps a photo journal of loaves. Bakers will appreciate precise hydration targets for different bread styles, one-tap starter logging, and a built-in recipe library with real photos — all designed to remove guesswork and make repeatable loaves easier to achieve at home.
