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.

Downloaded and used to check if I had interference with tower. I then downloaded other similar. Came back to this one. Use it with a booster to ensure I stay with 5g in my area. There are others I get switched to. Confidence in security and tech control makes me happy. Netmonster earned its fee !

I have paid for this and it did not deliver its services, it is trying to connect to a different ISP in my country UAE instead of my SIM card ISP provider when I set connection to NR. My ISP have NR + NSA CELLULAR COVERAGE. I have tried to untick the filter when searching for connections to my ISP but the software does not understand and still try to connect to a different ISP instead of my ISP which means I have no connection at all or phone calls
