Wifi Analyzer consists of five different screens that you can easily flip through. The initial screen (shown above) shows a graph of the available access points with their relative signal strength and Wifi channels being used. With this screen you can quick see available hotspots and which ones do not require security keys.
Before using the app, make sure that you have WiFi enabled on your device. Then, choose from multiple views to see current network performances.
