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. During collection it automatically attempts to guess location for each tower. 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:

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.

Love the app really cool, not someone who deals with mobile networking. Would love to see the ability for two or more phones to connect and by simulatiously taking measurments that are accurately time stampped create a more accurate location finding capabilities. I am not perticularly versed in the technology but I am sure you could as they say in csi and stuff "twaiangwuwaite" the signal.
