About this app

NetMonster collects, shows and stores information about nearby cell towers. Each tower has its unique set of identifiers and NetMonster will show you them. In select areas and countries precise locations are available.

All cells that your phone actively connected to are continuously saved into log till you terminate the app. You can manually correct the location, browse cells on the map, filter them and eventually export all the data.

NetMonster also visualises signal changes and provides short description what given measurement means and how it affects reception quality or theoretical maximal speed.

Supported networks are GSM, CDMA, WCDMA, TD-SCDMA, 4G LTE, 5G NSA and 5G SA. When it comes to LTE, NetMonster also detects aggregated carriers (so-called LTE-Advanced). For areas where 5G NSA is available you can see if NSA is in use or just deployed, carrier aggregation in 4G+5G NSA is also available.

NetMonster is based on open-source library NetMonster Core:

Ratings and reviews

Indeed this this app is very good: it shows information on neighbor carriers and the aggregated carriers, which I have not found in any other similar app I tried. Thank you! The UI is pretty simple but works. It would be GREAT if it would also show the CQI for each used carrier. Also it would be helpful if it would also show the LTE/NR band numbers (such as: 5, or n5), currently it shows the frequency band, like AWS for LTE band 4, or 700 for LTE Band 13.

Super complicated. No user documentation. After playing with it for a bit of time, all it ever displays is my T-Mobile phone, even though I have a Tracfone Doesn't seem to be any setting to select anything but a T-Mobile carrier. When I purchased this dumb app, it said it shows all the mobile networks around you. It does NOT do what it claims, but I guess for three stupid dollars, I get just three dollars worth of details. Lousy app.

Hmmm... Privacy policy - "NetMonster does not contain advertisements". Update app - oh look, consent screen for targeted ads, followed by ads. Checks changelog for mention of ads - nothing. I'm not against ads as such, as long as they're not too dominant, but why all the secrecy? That aside, the app is great and does pretty much what you'd expect (very handy for checking bandwidth in use), except for cell locations which are - at best - eclectic.
