Optimize your WiFi network using WiFi Analyzer (open-source) by examining surrounding WiFi networks, measuring their signal strength as well as identifying crowded channels.

Users' privacy and security is a huge concern these days and WiFi Analyzer (open-source) is designed to use as few permissions as possible. It asks for just enough to perform the analysis. Plus, it is all open source so nothing is hidden! Most notably, this application does not require access to internet, so you can be sure it does not send any personal/device information to any other source and it does not receive any information from other sources.

WiFi Analyzer is under active development by volunteers.
WiFi Analyzer is free, has no-ads and does not collect any personal information.
WiFi Analyzer is not a WiFi password cracking or phishing tool.
