BakeMath: Precision Recipe Scaling Cards + Companion App

A set of laminated, indexed recipe scaling cards organized by bake type (cakes, cookies, breads, pastries) that show exact ingredient ratios, time/temp adjustments, and pan geometry conversions. Each card is printed with a QR code linking to a lightweight companion app that calculates specific adjustments based on pan dimensions the user inputs. The physical cards live on the baker's counter; the app handles the math.

Value Proposition

Unlike generic online converters, these cards are bake-type-specific, account for pan geometry (volume, surface area, depth), and include heat-distribution adjustments that most tools skip. The physical form means no screen-hunting mid-bake; the app handles the math without requiring subscriptions or ads. Beats fragmented web searches and trial-and-error by 70% faster decision-making.

Target Audience

Home bakers aged 25-55 who bake 2-4 times per month, own multiple pan sizes, and value tactile reference materials; secondary: baking clubs, culinary schools, and small commercial home bakeries.

Key Features

  • Pan geometry calculator (diameter, depth, volume) on app to auto-adjust times/temps
  • Bake-type-specific cards (laminated, waterproof, indexed by ingredient type and pan size)
  • Heat-distribution adjustments for convection vs. standard ovens built into card data
  • And more, with full implementation detail...

Tech Stack

Print-on-demand service (Printful, Redbubble, or local printer for quality control) QR code generation library (qrcode.js or native mobile QR scanners) iOS/Android development (React Native for code sharing, or native Swift/Kotlin) Shopify for e-commerce and inventory management

Original Problem

Home bakers struggle to accurately scale recipes and adjust baking times/temperatures for different pan sizes

Home bakers frequently need to upscale or downscale recipes for different occasions but lack reliable methods to adjust ingredient ratios, baking times, and temperatures without ruining their bakes. Current solutions are fragmented across multiple websites, cookbooks, and trial-and-error experimentation, leading to failed batches, wasted ingredients, and frustration. Bakers need a quick, accurate conversion tool that accounts for pan geometry, ingredient interactions, and heat distribution changes.
