WhatsApp design blueprint — build a messaging app
The WhatsApp iOS app documented in full — chats, calls, status, communities, media viewer — with exact bubble styling, read receipts, and voice-note waveforms.
The reference blueprint for any messaging, calling, or groups app. Captures the minimal, chat-first surface that makes WhatsApp feel universally familiar.

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 WhatsApp blueprint translates cleanly into an Expo Router app structure.
