Recipe Portion Scaler — scale recipes to the servings you need
Recipe Portion Scaler is a recipe calculation and organisation utility from Three Two One Global. It helps you scale ingredient quantities for different serving sizes and keep recipes organised locally on your iPhone.
Scale ingredient quantities, paste ingredient lists, convert common measurements and save recipes locally — without turning cooking maths into a nutrition or medical tool.
A recipe-scaling utility — not medical, nutritional, allergy or food-safety advice.
Overview
A practical recipe serving calculator
Recipe Portion Scaler is built for a simple job: take the servings a recipe was written for, set the servings you need, and scale the ingredients accordingly. It is a measurement utility, not a cookbook, meal planner or nutrition app.
Recipe Portion Scaler is a recipe calculation and organisation utility from Three Two One Global. Enter original and desired servings, add or paste ingredients, review parsed results, convert supported units and save recipes locally — with an optional lifetime unlock for unlimited saved recipes.
