inSSIDer is the best option, for Windows en Android.

Nowhere to be found on Play Store. It should be this link:

But it's dead.

And I'm guessing it came/comes with ads.

Yes I didn't find InSSIDer on Play Store when I looked recently. I certainly
downloaded and installed it from there at some time in the past, so it looks
as if the makers have removed it - maybe because they want to sell the later
version rather than give away the older version. I wonder if anyone has
saved the older installation file and put it on the internet somewhere.

But WifiAnalyser (by Keuwlsoft) is still available. That also gives details
of relative signal strengths of signals in range, and it plots a graph of
the strength versus time so you can see how the strength varies as you walk
around.
