Webull
A design blueprint Spectr produced from Webull. Scroll to look closer.
A dark-native trading terminal where the candlestick chart and order ladder lead
A pixel-faithful design token catalog reverse-engineered from the Webull iOS app, built around the quote spine: a colored tabular last price, a full-bleed candlestick chart with a timeframe strip, the bid/ask order-book ladder, and a watchlist of sparkline rows. Captured from a real screen recording into the exact Webull blue→cyan gradient, near-black terminal canvas, and pervasive up/down color, ready for an AI agent to build against.
Use it as the baseline to ship a Webull-grade trading terminal: the quotes-to-chart-to-trade spine, candlestick chart with indicators, the depth-bar order ladder, the options chain, and the split Buy/Sell docked pair. Everything is documented to exact values — `#1B9EFB → #20D5C4` brand gradient, the `#0B0E11` dark-native canvas, sacred up `#00C076` / down `#FA5252`, the cyan PAPER badge, region-aware up/down, tabular money, radius scale, and motion — 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 Webull blueprint translates cleanly into an Expo Router app structure.
