Scale any recipe to any serving count. Paste text or snap a cookbook photo — quantities re-portion with kitchen-real rounding, units flip metric/US, missing ingredients get swaps.
Like a cook, not a calculator. Cups and spoons round to eighths, eggs round to whole eggs, metric grams round to sensible figures. Scaling a 4-serving recipe to 6 gives you "1 ½ cups", never "1.4999 cups".
The built-in table covers the classic baking and cooking swaps — buttermilk, eggs, brown sugar, cake flour, baking powder, heavy cream, fresh herbs, wine, and about twenty more. Tap the swap icon next to a matched ingredient to see the ratio.
Printed cookbook pages and screenshots work well. Handwriting is hit-or-miss — paste the text instead when you can.
Not yet — serving count and direct multipliers only. Pan-area scaling is on the list.
