RecipeScale: Ingredient Auto-Adjuster
Instantly scales recipe ingredients and recalculates cooking times when you change serving sizes, with smart unit conversion and pantry-substitution suggestions.
The Problem
Home cooks constantly struggle with math when scaling recipes up or down—converting cups to grams, adjusting bake times, or figuring out substitutions. Most recipe apps don't handle unit conversions well, and no app intelligently suggests ingredient swaps based on what's actually in your kitchen.
Target Audience
Home cooks aged 25-55 who cook 3+ times per week, meal-preppers, parents managing family dinner sizes, and recipe hobbyists who use Pinterest/AllRecipes daily.
Why Now?
LLMs make intelligent substitution suggestions viable (e.g., 'no buttermilk? use yogurt + lemon') without manual recipe databases. Recipe content is freely available via APIs or web scraping. Mobile-first food tech is booming post-pandemic.
What's Missing
Existing recipe apps treat scaling as an afterthought—they show serving size but don't adjust times or suggest substitutions. No app bridges the gap between 'I have 3 eggs instead of 4' and 'here's what to do differently.'
