Wifi Analyzer helps you get a better understanding of the Wi-Fi networks in your area.

It is a very simple tool to help you determine a Wi-Fi's signal strength by providing you a graphical representation of the signal power, Wi-Fi band, security, and SSID. It also identifies nearby access points and channels with traffic build-up. Moreover, it provides an estimated distance to the nearest available server.

This app works in the background and requires few permissions. This means that it does not need to access your data. And with an easy-to-use interface, it does not require any special knowledge to use it.
