QRMaple makes QR codes you can change after printing. Print one on a menu, flyer, or package, then change where it points any time without reprinting. Paid plans are a one-time purchase, not a subscription, with unlimited codes and scans. See which QR code gets scanned and when (by day, hour, and weekday), plus full design and bulk creation from CSV. A plain black-and-white QR generator is free with no sign-up.
