WifiAnalyzer, great for finessing your own WiFi channels by providing a scan layout of all 2.4Ghz and 5/6Ghz channels in your area.
You can see bandwidth, signal strength, overlapping networks, everything.
I use it to diagnose deadspots in my home, or to search for hidden wireless cameras in hotel rooms
It used to have a feature that would beep faster the closer you got to an AP. I used it in cafes and libraries to figure out where to sit for the best WiFi. But they killed it, and I have no idea why :'(
I think it’s an OS limitation which throttles the Wifi scanning to slower intervals (and also requires you to enable location(??))
That doesn’t make sense to me. I have root. I should be able to allow the app any scanning interval I want.
I think you can disable the “WiFi scan throttling” option in the Developer Options, which might remove this default limitation
Still no idea why Location is needed for this
Edit: Apparently it’s a safety feature against malicious developers who can pinpoint your location based on scan results. To make the user aware, they force you to enable location permission
