Quick answer
Reconstruct damaged or blurry QR codes entirely on-device for easy scanning.
QR Code Displayer generates a clean, easy-to-scan version of any QR code.
The app works like this: * You select an image containing a QR code on your phone or "share" it to this app. * The app decodes the original code using math! * A brand new, high-resolution QR code is generated containing the exact same content. * The new code is drawn with black edges on a white background. * You then have the option to enter display mode, where screen brightness is maximized and stays awake to assist with scanning. * You also can give your new QR code a title and save it to use later. * Or even see what is the content of the qr code and copy it!
You can alternatively type in some text to create a QR code containing that.
This app is fully open-source, contains no ads or unnecessary permissions, and processes all data entirely offline on your own device.

- If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
