AndrQR lets you generate QR codes to:
Share contact information;
Share WiFi details;
Share payment details (such as Bitcoin and PayPal payments);
Share website links;
Share e-mails and e-mail addresses.
You can also print the QR Codes you generate to your printer, save them as favourites or customise advance settings such as the QR code's size and error correction levels.
Furthermore, all QR codes are generated offline. No internet connection is required!
AndQR uses a Material Design and is an alternative to QR Droid Private and other QR Code Generator apps.
