Baker-style flour accounting, target dough/flour budgets and a rounding audit.

CrumbScale is for scaling a formula you have already tested. It separates flour and water contributed by a preferment from the rest of the mix, then shows exact and scale-rounded quantities. It is a calculation tool, not a recipe, fermentation or food-safety adviser.

What it does

• Enter final-mix ingredient weights once. A ready flour-water preferment is entered as its total weight and hydration.
• The app decomposes preferment flour and water for accounting; do not re-enter that flour/water as separate ingredients.
• Scale by number of pieces × raw-dough grams per piece or by a total flour budget, including flour inside preferments.
• Inspect formula ratios, exact scaled values and separate rounded weighing quantities.
• Choose nearest 0.1 g, 1 g or 5 g scale resolution. Tiny ingredients that round to zero are highlighted.
• Rounding differences remain visible; the app does not silently move a difference into another ingredient.
• Undo up to 30 saved states and capture a single summary comparison.
• Save editable JSON, a TXT weighing card or a CSV audit report.

A practical workflow

1. Use your tested formula and enter what actually goes into the final mix.
2. Identify flour-water preferments with their true total weights and hydrations, avoiding duplicate flour/water entries.
3. Choose a dough-piece target or total-flour target and the resolution of your scale.
4. Review exact versus rounded amounts, especially small ingredients, before using the weighing card.

A worked use case

A 200 g preferment at 100% hydration contributes 100 g flour and 100 g water. Entering that same flour and water again in the mix would double-count them; the separate preferment entry prevents that bookkeeping mistake.

What you can keep

• Editable JSON
• TXT weighing card
• CSV exact/rounded audit

Formula data and exports are processed locally. Refreshing or closing loses unsaved formulas and undo history.

What it does not promise

• Other ingredients contribute weight, but water in milk, eggs or similar ingredients is not inferred.
• Raw dough weight is not baked weight. Fermentation time, cooking method and safe handling are not estimated.
• A summary comparison is not a complete editable backup; keep JSON.
