YouTube design blueprint — build a video platform app
A full spec of the YouTube iOS app — home, Shorts, subscriptions, watch page, comments, library — with exact player controls, chapter markers, and subscribe buttons documented.
The definitive blueprint for any long-form video, creator, or streaming app. Covers the mini-player swipe, Shorts rail, and comment-tree at pixel fidelity.

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 YouTube blueprint translates cleanly into an Expo Router app structure.
