CrumbScale: Baker Percentages
Bread math & bake journal
$3.99 · Designed for iPad. Not verified for macOS.
A calmer way to scale bread: accurate starter accounting, saved formulas and an offline bake journal.
Make the batch you actually want. CrumbScale brings clear baker’s percentages, accurate sourdough starter accounting, and a personal bake journal to your iPhone and iPad.
PRECISE DOUGH MATH
Scale to a target mixed dough weight or total flour weight. Adjust hydration, salt, starter weight and starter hydration. CrumbScale counts the flour and water inside your starter, then shows exactly how much flour and water to add. Add optional yeast, oil or butter, and sugar by percentage. Invalid combinations are explained before you save.
YOUR RECIPE SHELF
Save, edit and delete recipes with your own method notes. Clearly labeled sample formulas help you get started. Share a plain-text ingredient list through the system share sheet.
REMEMBER EACH BAKE
Keep a dated journal with bake names, personal ratings and observations about fermentation, crust and crumb. Revisit and edit entries as you learn.
BAKING FIELD NOTES
An original offline reference explains baker’s percentages, starter hydration, batch targets, enrichment and useful bake notes.
FULLY OFFLINE
No account, ads, analytics, subscriptions or in-app purchases. Your recipes and notes are stored on your device and may be included in device backups.
All calculations use grams. Total hydration includes added water and starter water; water in other ingredients such as milk, eggs and butter is not estimated. Dough weight is mixed weight, not final baked loaf weight. Baking times and results vary with flour, temperature and technique.
