that says it collects some data!
Well Net Signal Pro very well could be collecting data as well. What you see on the playstore listing is just a declaration. Google doesn't actually check if the app is collecting data or not.
well damn !
thought that thing was useful but if what u say is true it's blabber!
This one free too:
WiFi Analyzer (open-source)
https://play.google.com/store/apps/details?id=com.vrem.wifia…Not free (with ads) but also a good app to figure out your cell tower locaitons etc
CellMapper displays advanced 2G/3G/4G/5G (NSA and SA) cellular network information and can also record this data to allow you to contribute to our crowd-sourced coverage maps.
https://play.google.com/store/apps/details?id=cellmapper.net…i love opensrc software that doesn't track data 💕
And here's to the good hearted geeks who create it
I installed the deal but Wi-Fi analyser is much more useful
For IOS
Opensignal app: this is similar to Cellmapper, but might not be as detailed.

Call mapper linked above
What about Network cell info lite?

Many new phones come with this in-built in 'WiFi Developer Options' or a similar settings page.
Shows 0.99 for me
Me too.
As does Wifiman which is always free…
