ScanFi is a useful wireless network analyzer that allows you to scan your wireless network without connecting to any access point. This app turns your Android phone into a passive scanning device and provides all the details along with cool graphical representations. It is an excellent tool for anyone who wants to know more about their Wi-Fi network.

With ScanFi, you can scan your wireless network for available access points, get information about their signal strength, SSID, MAC, and much more. You can also get information about a specific access point, along with a history graph for 60 seconds. The app features cool graphs that show all the activity on your WiFi network and channel ratings that help you identify the least crowded channel for transmission.

ScanFi also allows you to create a Wifi strength survey of your house or apartment with default or custom floor maps that you can load from your gallery. You can check your average download speed and know only the open access points around you. The app can also search for unknown or hidden access points.

It is important to note that this application is just an analyzer and not a WiFi connection tool. Additionally, the 2.4GHz or 5GHz scanning capability needs to be present in the Android device hardware. Overall, ScanFi is a great app that provides all the necessary information about your WiFi network.
