RecipeScaler
Cooking for two tonight, or twelve this weekend? Tell RecipeScaler how many you're feeding and it rescales every ingredient for you — in real fractions, not weird decimals.
RecipeScaler is a free iPhone app that scales any recipe to the number of servings you actually need — and scans printed recipe cards with your camera.
No account. No internet. No little notepad of scribbled "okay so if I want 1.5 batches…" math. Just the amounts you need, ready to cook.
Punch in the servings — or hit the quick buttons — and every ingredient updates at once. Halving dinner for just you? Done. Tripling cookies for the bake sale? Also done.
Got a recipe on paper or in a cookbook? Snap a photo and RecipeScaler reads the ingredients straight off the page, so you're not retyping a thing.
You get "¼ cup," not "0.25 cups." And when a recipe's in grams but your measuring cups aren't, the built-in converter sorts it out.
That stained index card from your mom, a photo from a cookbook, a printout from a website — snap it and the ingredients land in the app, ready to scale. It all happens right on your phone, so nothing gets uploaded anywhere.
Cups, tablespoons, teaspoons, fluid ounces, milliliters, liters, grams, kilograms, ounces, pounds — convert between any of them without leaving the kitchen to go look it up. Nice and quick when you're mid-recipe with floury hands.
Yep. Scaling recipes, scanning cards, and the unit converter are all free to use. There's an optional one-time $1.99 Pro upgrade (not a subscription) if you want unlimited saved recipes, a shopping list, and a full-screen Cook Mode that keeps your screen awake while you cook.
It does. Everything runs right on your iPhone — no account, no sign-in, no connection needed. You can scale a recipe on a plane or in a cabin with zero bars.
You take a photo of a printed recipe — a card, a cookbook page, a printout. The app reads the ingredients using Apple's on-device text recognition and drops them into a list you can scale instantly. The photo never leaves your phone.
Yes — the built-in converter moves between cups, tablespoons, teaspoons, fluid ounces, milliliters, liters, grams, kilograms, ounces, and pounds. And it shows everything as tidy fractions instead of long decimals.
There's nothing to worry about here. No data collection, no tracking, no ads, no account. Your recipes and photos stay on your device, full stop.
Real recipes we actually cook at home — scan or scale any of them right in the app.
