Convenience: No need to have the QR code once you scanned it once. It is automatically saved in the app history until you choose to delete it. This way you can visit that page over and over again. More than that, you can copy all the URL's in the app and paste them to your Notes or email for sending them to your friends and family, or just to bookmark them on your computer browser.
