But why is the app called QuiRksheets? Well... this app is actually just a small part of a larger "work-in-progress" which runs on desktop (and eventually tablets) for creating editable worksheets that contain QR codes. I use these with students and was looking for an easy way to save and edit this kind of worksheet... including the QR codes embedded in them. For students to use these worksheets I needed a QR code scanner that met the specs listed above. Hence, this app and its unlikely name.
