Visual WiFi RADAR to show the approximate location of WiFi access points in the vicinity of your phone. Designed to work with ordinary WiFi enabled Android phones with built in e-compass facility. The RADAR plot is constructed by a slow rotation (the slower the better) of the person holding the phone in front of them. The RADAR plot then visually represents the approximate direction and range of the WiFi access points discovered (in relation to the red cross). A map facility enables approximate location with respect to the currently connected AP to be tracked.
