Link QR Wallet turns URLs into QR codes and stores them in a searchable, sortable library on the device. Add a link, optionally tap Fetch Title to fill in the page title, and the app generates a QR code that can be shared as an image or scanned back in. Links can be searched and sorted by title, domain, or date. A built-in scanner reads existing QR codes so codes made elsewhere can be imported into the same library. All data is stored locally; nothing is sent to a server. The app uses the camera only to scan QR codes and the network only to fetch a page's title when you tap Fetch Title. Nothing goes over the network while you type, scan or share a link.
