Simple question:

Q: Which app do you use on iOS or Android to figure out all the cellular
towers and signal strengths of the cellular signal (CDMA or GSM) in your
area?

Q: Does that app show you *all* the towers that your phone can see
(or does it only show the one tower that your phone is connected to)?

On Android, I am currently testing these GSM/CDMA signal strength apps,
where you can see my actual screenshot results in the photos below.

01 Network Cell Info Lite, version 3.30:

07 WiGle WiFi Wardriving (which also reports cellular towers):

08. OpenSignal, version 5.10:

etc.

On iOs, I looked for similar apps, and found this:

01 OpenSignal, version 4.0.5 (but it doesn't seem to report the nearby
tower and signal strength):

The one bad thing is that all these apps only show one cellular tower, even
though I know I have *two* microtowers inside my house, so, I think I need
to find a better app which will show *all* the cellular towers it sees.

To that end, I ask this scientific debugging question:

Q: Which app do you use on iOS or Android to figure out all the cellular
towers and signal strengths of the cellular signal (CDMA or GSM) in your
area?

Q: Does that app show you *all* the towers that your phone can see
(or does it only show the one tower that your phone is connected to)?
