You can make your QR-code from any text in any language with any numbers you need for any goal. It was created using Flutter/Dart. This app does not contain any adds or telemetry and open source. Source code can be found here: https://github.com/I-am-a-squirrel/qr_coder. If you want to add something to this app I will wait for your ideas.
This app is using 7th generation of QR-codes with all its advanntages and restrictions.
