Bake better bread with the numbers done for you

Free calculators for home bakers. No sign-up, no ads, and they work offline once loaded.

Hydration & baker’s percentage

Enter your flour, water, salt and starter to see true dough hydration, with the flour and water inside your levain counted. Or start from a target and get the grams.

Recipe scaler

Double a recipe, halve it, or scale it to an exact dough weight. Ratios stay exact; only the display is rounded.

Sourdough schedule planner

Work back from when you want bread. Feeding, mixing, bulk, shaping and baking times, adjusted for your kitchen’s temperature, with what to look for at each step.

Starter tracker

Log feedings, ratios and time to peak. Private to your device, with exports you can save as backups. Browser data can be cleared.

More tools are on the way: dough temperature and pan-size conversions.
