MyFitnessPal design blueprint — build a clinical calorie + macro app
A full spec of the MyFitnessPal iOS app — diary, calorie ring, macro trio, barcode scan, food search — captured with the MFP Blue heritage palette, locked macro colors, and color-flipping calorie ring.
A starting blueprint for any calorie-tracking, macro-counting, nutrition, or meal-logging app. The 220pt ring that color-flips by state and the locked Carbs/Fat/Protein trio are documented in full.

What a Spectr spec includes
Screen-by-screen documentation, complete design system (color, typography, spacing), navigation map, component library, implementation notes, and a Claude Code prompt — everything an AI coding agent needs to build.
Turnaround
Most mobile apps produce a full spec in under 90 seconds from a single screen recording. Upload your own MP4 and watch the blueprint generate live.
Why not a design file?
Design files don't compile. A Spectr spec is optimized for AI coding agents like Claude Code — it produces working code on the first prompt, not layered artboards.
Target stack
Every spec targets Expo SDK 54 and React Native on an iPhone 15 baseline. The MyFitnessPal blueprint translates cleanly into an Expo Router app structure.
