"Mannaka" is a free QR code reading app. Its feature is that it only reads the QR code in the center of the preview screen. Among the many excellent QR code reading apps, there are some that invite you to the "App Store" even though you think you have read the QR code that goes to "Google Play". These QR code reading apps read the QR code captured by the camera that is in a place where the app itself can read it easily, not the QR code I want to read, and make a smug face.
And sometimes, even though I want to read a QR code, it reads an unrelated barcode around it and makes a smug face. I can't stand it anymore. I decided to make an app that can read only the QR code I want to read. This app only reads the QR code in the center of the screen. And it only has the function to copy the read URL and pass it to the browser. Because I only use this app to read the QR code and view the URL in the browser. I'm not young anymore, so if there are too many functions, I don't know what's what.
