ColorInvo

Put your Taiwan mobile invoice carrier on the iPhone Home Screen, with colors that match your wallpaper and settings that stay on device.

  • Carrier barcode

    Save your carrier once. The app validates the format and creates a Code 39 barcode for checkout scanning.

  • Home Screen widget

    Add the widget to your iPhone Home Screen so the barcode is ready without opening the invoice app.

  • On-device setup

    Wallpaper color generation and widget settings stay on your device. No account, ads, or backend service.
