Cal AI design blueprint — build an AI calorie-tracking app
A full mobile UI spec of Cal AI — onboarding, camera capture, macro breakdowns, streak tracking — reverse-engineered frame by frame so you can ship a visually comparable app.
The ideal baseline for any AI-powered food, fitness, or health tracker. The blueprint covers every empty state, loading shimmer, and micro-interaction across the core flows.
Screens documented
- Onboarding + goal setup
- Scan a meal (camera)
- Macro + calorie breakdown
- Daily log
- Streak + progress
- Settings + profile
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 Cal AI blueprint translates cleanly into an Expo Router app structure.
