WiFi Analyzer (open-source)

About this app

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.

Notes:
- Android 9 introduced Wi-Fi scan throttling. Android 10 has a new developer option to toggle the throttling off under (Settings > Developer Options > Networking > Wi-Fi scan throttling).
- Android 9.0+ requires location permission and location services to perform a WiFi scan.

Ratings and reviews

The devs on this app do great work, unlike all the other trash apps out there with obnoxious and intrusive ads. No ads on this one, just analyzing 2.4, 5 and 6 GHz. Simple and efficient. Keep up the good work, devs. We appreciate you. You should be the ones at the very top of the list when people search for wifi analyzing apps, not all the other garbage apps.

Seems like this app never refreshes its screens. I've changed the wifi bands on the router, and no matter what I do the app screen never refreshes to show the changes. (On my laptop and on the router itself, I can view the updated connection and band). So it's basically useless, even if you kill the app and reload from scratch Yes, I disabled the scanning throttling thing

I cannot stress how useful this app is out in the field as a commercial business cable technician. With Wi-Fi throttling disabled, the amount of information that this app provides has become paramount on many jobs. I use it mostly to tell if access points are broadcasting, or how many a customer may have that they are unaware of. I can tell what type of Wi-Fi they are broadcasting, how many access points they may have, and in most cases, what brand or Carrier they may be using.
