About this app

Your favourite recipe makes 12 cookies. You need 40. Do the math — or just use Recipe Batch Scaler.

Type in your ingredient list once. Tell the app how many servings you want. Every measurement scales up or down instantly, keeping every ratio exactly right. No calculator juggling. No scribbled fractions. No ruined batches.

WHAT IT DOES
─────────────────────────────────

✦ Scale Any Recipe Instantly
Enter your original serving size and your target. The multiplier is calculated for you — 2× , 0.5×, 3.75× — and every ingredient updates in real time as you type.

✦ Full Ingredient List Editor
Build a proper ingredient list with quantities, units, and names. Drag rows to reorder them. Swipe to delete. Every ingredient scales together, never individually.

✦ Smart Unit Conversion
Switch your entire recipe between metric and imperial in one tap. Grams become ounces, litres become cups — and the app always picks the most human-friendly unit. 480 ml becomes 2 cups, not 32 tablespoons.

✦ Fraction Display Mode
Toggle between decimal output and proper cooking fractions. 0.333 becomes ⅓. 1.75 becomes 1¾. Your recipe reads like a recipe, not a spreadsheet.

✦ "To Taste" Awareness
Salt, pepper, and any ingredient marked as "to taste" never gets scaled. Because nobody wants "0.375 pinches of cumin."

✦ Save Your Recipes
Build a personal recipe library. Every recipe is saved with its name, original serving size, and your preferred target — ready to load and rescale any time.

✦ 5 Built-In Starter Recipes
Hit the ground running with a white bread loaf, chocolate chip cookies, classic pancakes, tomato pasta sauce, and banana bread — all pre-loaded with accurate measurements.

HOW IT WORKS
─────────────────────────────────

1. Name your recipe and set the original serving size.
2. Add ingredients — quantity, unit, and name.
3. Set your target serving count.
4. Watch every measurement update instantly.
5. Copy, share, or save the scaled recipe. Done.

The app recalculates everything live as you adjust the serving numbers. Change your target from 4 to 7 and all 12 ingredients update before your finger lifts.

SMART UNITS THAT MAKE SENSE
─────────────────────────────────

Recipe Batch Scaler knows the difference between a cup and a tablespoon. When a scaled quantity becomes large enough to express in a bigger unit, it promotes it automatically — so you read "2 cups" instead of "473 ml", and "1.2 kg" instead of "1200 g".

Supports: ml, cl, dl, L, tsp, tbsp, fl oz, cup, pint, quart, gallon, g, kg, oz, lb — plus count units like pieces, cloves, pinches, cans, and sprigs.
