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

    search for hidden wireless cameras in hotel rooms

    Wow, how do you find them? Have you actually had success?

    I went to an airbnb that had a creepy but visible proximity sensor in the bedroom, and a hidden wifi network that was strong near it.

    So, I found a network for an already visible device :-)

    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
