RecipeScale: Ingredient Ratio Adjuster
AI-powered app that instantly scales recipes up/down while adjusting cooking times, temperatures, and ingredient substitutions for dietary restrictions.
The Problem
Home cooks constantly struggle with recipe scaling — dividing ingredients by 3 for a smaller batch introduces math errors, and scaling affects cooking chemistry (baking is especially finicky). Existing recipe apps either don't scale properly or require manual math. People with allergies need instant substitution suggestions when scaling, which no current tool provides.
Target Audience
Home cooks aged 25-55 who meal prep, people with dietary restrictions (gluten-free, vegan, keto), busy parents scaling recipes down to avoid waste, and amateur bakers who need precision.
Why Now?
Claude's vision API can now parse recipes from photos, and people are increasingly conscious of food waste and dietary needs — scaling recipes properly is suddenly more valuable.
What's Missing
Current recipe apps treat scaling as a one-liner feature, ignoring cooking chemistry and dietary swaps. No tool understands that scaling 'flour' from 2 cups to 0.5 cups requires density adjustments and baking soda tweaks.
