A design blueprint Spectr produced from Facebook. Scroll to look closer.
Facebook UI blueprint — build a social network app
The Facebook iOS app captured screen by screen — News Feed, Stories, Marketplace, Groups, Reels, notifications — with exact typography, spacing, and card anatomy.
The canonical blueprint for any large-scale social-network app. Covers the full information architecture: feed composition, reactions, comments, and cross-linked surfaces.
Screens documented
- News Feed

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 Facebook blueprint translates cleanly into an Expo Router app structure.
