Signal UI blueprint — build a privacy-first messaging app
A complete spec of the Signal iOS app — the chat list, encrypted bubbles, disappearing-message timers, and calls — captured with the single Signal-blue accent and zero-vanity minimalism.
The reference for any encrypted, privacy-focused, or secure-comms app. The bubble system, disappearing timer chip, and sealed-sender glyphs are documented in full.
Screens documented
- Chat list
- Conversation
- Disappearing messages

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 Signal blueprint translates cleanly into an Expo Router app structure.
