You’ll see that Qrafter now has two versions, Qrafter and Qrafter Pro. Qrafter is a FREE app and Qrafter Pro is $3.99. Why two versions?
The two apps share the exact same code base and have the same abilities. Qrafter is supported by ads which can be removed by purchasing its in app purchase called Pro Pack. Qrafter Pro on the other hand, comes with Pro Pack enabled when you purchase it.
So if you want to have the best QR Code app for iOS or iPadOS that can both scan and generate QR Codes along with Data Matrix, Aztec Codes, PDF417 and various other barcode formats, while being completely FREE with ad support, download Qrafter. If you don’t want to see ads, purchase Pro Pack directly inside Qrafter or uninstall the app and purchase Qrafter Pro.
Qrafter Pro was created so that educational institutions can benefit from volume purchases. Also some people like to purchase full apps directly from the App Store instead of using in app purchases. So these two versions will cover all bases.
