Is there an app that logs the signal strength of public WLANs near me, those that I see in the Wifi Dialog of my Phone, when I walk around in some area? It should draw the approximate location of the WLAN router on some map, Openstreetmap for instance.
It is pretty easy to do this manually., "in your head" , just by walking, when you see the decibel value showing up, then getting stronger, taking on some maximum, then disappearing again.
I am not so much interested in signal strengths from the cell towers of the Phone Companies.
The wifi location does not need to be that accurate, and does not have to be displayed in real-time. Could happen after some specified interval: "start logging WLANs" ...take a walk... "end logging WLANs". Then after the walk , "process log".
There are so many WLAN apps in the Play Store that I don't know which to choose.
Perhaps this can be accomplished with a completey different service, no idea.
