Setup checklist

• Open ColorInvo and enter the 8-character carrier after the leading slash.
• Choose barcode colors, or generate colors from a wallpaper photo on device.
• Save, then add the ColorInvo widget from the iOS Home Screen widget picker.

Common issues

• Widget does not show the barcode

  Reopen ColorInvo, confirm that the carrier format is valid, save again, then wait for iOS to refresh the widget.

• Wallpaper colors cannot be generated

  Choose a still image from Photos. The image is only used for local color generation and preview, and is not uploaded to ColorInvo.

• Barcode scan fails at checkout

  Use a higher-contrast color choice and avoid red bars. Store scanners commonly use red light, so red bars can reduce readability.

Bug reports
