What Gramwise does
Every cup-to-gram converter on the App Store assumes a cup of sugar equals a cup of flour — they don't. They assume an egg is just 'an egg' — large vs jumbo varies 14g. And almost none handle real bakers' edge cases (packed brown sugar, sifted flour, softened butter). Gramwise has the data tables you actually need: — 200+ ingredients with USDA-derived weight-per-volume data. — Eggs sized correctly (small / medium / large / extra-large / jumbo), in / out of shell, separated yolk vs white. — Butter: sticks, tablespoons, cups, sliced cubes — all to grams. — Sugars: granulated, brown packed/loose, powdered sifted/unsifted. — Flours: all-purpose spooned vs scooped, bread, almond, oat — different weights. — Liquids: water, milk, oil, honey — density adjusts the conversion. Plus a recipe scaler: paste in a recipe, set new servings, get every quantity scaled AND converted between cup/metric in a side-by-side view. Free, on-device, no subscription. Density tables ship in the binary. No internet. Works offline in your kitchen forever.

Why it exists
The problem
Existing cup/gram converters use a single global density (e.g. 240g per cup) regardless of ingredient. Cupify users report 'a cup of sugar weighs anywhere from 7-8 ounces' because the app sliders are linked to volume not ingredient — totally wrong. Cooking Units Converter pro features simply don't work. Apple's secret…
