Sourdough Calculator & Journal

Sourdough Calculator & Journal is a compact baking utility that handles the math and scheduling behind every sourdough loaf, whether you bake casually or run a small bakery. The app combines a baker's-percentage calculator, a hydration estimator that includes starter water, a starter feeding manager with reminders, a bake-timeline planner with step timers, recipe scaling and a photo journal for logged bakes. You may want it to remove guesswork—automated percentages, clear step sequencing and built-in templates make consistent results easier. The app works offline with no account required and supports metric or imperial units.
