RecipeScaler: Scale Any Recipe

Snap a photo of any recipe card. Watch every ingredient scale to the servings you actually need. Cook from a checklist that keeps your screen awake.

RecipeScaler is the recipe-scaling calculator that does the math for you — including the camera scan that turns a printed recipe into a perfectly scaled ingredient list in seconds. All on-device, no internet, no account.

HOW IT WORKS

1. Photograph a recipe card, or type ingredients by hand
2. Set the original servings and how many you actually need
3. Every measurement re-scales as clean fractions (½ cup, ¼ tsp — never ugly decimals)
4. Save it, cook from it, or pull it into your shopping list
