Sleep Cycle
A design blueprint Spectr produced from Sleep Cycle. Scroll to look closer.
Indigo night gradient, the glowing hypnogram wave, sleep-quality ring, and smart alarm
A pixel-faithful design token catalog reverse-engineered from Sleep Cycle iOS, built around the signature sleep-analysis graph: a smooth glowing aqua wave over color-coded stages, the sleep-quality ring, and the smart-alarm card. Real night-gradient palette, heavy rounded Nunito numerals on a deep low-glare canvas.
Everything you need to ship a Sleep Cycle-grade sleep tracker front end: exact hex values, the bezier hypnogram with stage colors, the score-banded quality ring, the smart-alarm wake window, and the colored-glow primary button. 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 Sleep Cycle blueprint translates cleanly into an Expo Router app structure.
