QR Code Displayer

Reconstruct damaged or blurry QR codes entirely on-device for easy scanning.
New in version 1.4.1
- Made long screens scrollable so all actions are reachable.
- Made status bar information visible from within the app.
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.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
