A design blueprint Spectr produced from Fitbit. Scroll to look closer.
A supportive health dashboard where every metric owns a color and the big number is the hero
A pixel-faithful design token catalog reverse-engineered from Fitbit iOS, built around the Today dashboard: the steps ring hero, the metric tile grid, the Sleep score, and Daily Readiness. Real teal-black canvas, a per-metric color system, and warm DM Sans coaching copy.
Everything you need to ship a Fitbit-grade health app: exact hex values, the sweeping steps progress ring, color-coded metric tiles, the 0-100 Sleep and Daily Readiness scores, and pill CTAs with ring-sweep and count-up motion. Comes with framework-neutral specs plus SwiftUI, Expo, and Jetpack Compose guides.

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 Fitbit blueprint translates cleanly into an Expo Router app structure.
