ColorInvo

Make your Taiwan mobile invoice carrier barcode match your wallpaper.

繁體中文

Why

• Instant Barcode Access: Show your invoice barcode in a second with an iOS widget.
• Wallpaper-Based Theming: Pick a wallpaper, and the app extracts representative colors and a small preview to generate matching themes.
• Guaranteed Scannability: Barcode colors are generated to meet commercial scanner reflectance and contrast requirements.

We plan to release this to App Store in the future, hold on tight!

Web deployment

The root vercel.json is the single deployment definition. Vercel installs the apps/web workspace, runs the root web:build script, and publishes the static export from apps/web/dist. Do not add a second config under apps/web.

Run on iOS Simulator

Build ColorInvo, boot and open an available iPhone simulator, install the app, and launch it:

bun run simulator

Codex simulator screenshots

To send a visible iOS Simulator screenshot in Codex chat, capture the booted simulator and attach the PNG bytes to the chat result instead of linking to a local Mac path:

bun run ios:screenshot-chat

The script writes an absolute PNG path under .codex-screenshots/ and prints a node_repl snippet. Run that snippet with the node_repl js tool so Codex chat receives the image bytes through nodeRepl.emitImage(...); this makes the screenshot viewable from Codex mobile too.
