Strong
A design blueprint Spectr produced from Strong. Scroll to look closer.
Strong Blue on flat neutral dark, the set-log table, slim rest bar, and amber PR flags
A pixel-faithful design token catalog reverse-engineered from Strong iOS, built around its famously minimal set-log table: tabular-figure cells, the Previous column, a slim auto-running rest-timer bar, and flat borderless exercise cards. Real single-accent palette with neutral-grey surfaces and Inter type tuned for arm’s-length reading.
Everything you need to ship a Strong-grade workout logger front end: exact hex values, the Set/Previous/kg/Reps grid, the slim rest-timer progress bar, set-done green fill, and the amber PR flag. 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 Strong blueprint translates cleanly into an Expo Router app structure.
