Many QR codes are designed to initiate an action such as visiting a website, sending a text message or joining a WiFi network, but just from looking at the code, a square array of black and white patches, the user has no idea what the code contains. With this app, after scanning a QR, you first can see easily what the code is planning to do before activating it, save the code for later use, share it with others or edit the contents. Furthermore, you can easily generate QR codes yourself to give information -- such as how to join your network -- to friends and colleagues.
