NetMonster

NetMonster collects, displays, and stores detailed information about the cell towers surrounding you. It reads the unique identifiers that each tower broadcasts, then shows them clearly on your screen.

You finally get a plain answer to a question every phone user wonders: which towers am I actually connected to, and how strong are they?

In select areas and countries, NetMonster even calculates the precise location of each tower, so you can track exactly where a signal originates.

Continuous Cell Logging

NetMonster records every cell your phone actively connects to. It stores these entries in a continuous log that runs for as long as the app stays open, and it keeps collecting data until you terminate it.

You review the log at any time, so you can see exactly how your connection shifted during a drive, a commute, or a walk through a dead zone.

Correct Locations Manually

GPS gets unreliable indoors and in dense cities, so NetMonster lets you override it. You manually correct the location of any reading to make sure your data maps to the right place.

That control matters when you build a personal database of weak-signal areas.

Map, Filter, and Export Your Data

NetMonster turns raw readings into something you can work with.

You browse cells directly on the map, apply filters to isolate specific network types or signal ranges, and export the entire dataset when you are ready.

That export capability makes the app valuable for anyone who documents coverage, tests hardware, or simply likes to keep records.

Visualise Signal Changes in Real Time

NetMonster does not just print numbers. It visualises how your signal rises and falls over time, which reveals patterns you would never catch by watching the status bar.

Better still, the app explains each measurement. Every value comes with a short description telling you what it means, how it affects reception quality, and what theoretical maximum speed it supports.

Full Support Across Generations

NetMonster covers the full spread of cellular technologies:

• GSM
• CDMA
• WCDMA
• TD-SCDMA
• 4G LTE
• 5G NSA
• 5G SA

Detect LTE-Advanced Carrier Aggregation

For LTE, NetMonster goes a step further. It detects aggregated carriers, commonly known as LTE-Advanced.

You can see when your phone combines multiple frequency bands to boost throughput, rather than guessing why a download suddenly feels faster.

Track 5G NSA Deployment and Aggregation

In areas where 5G NSA is available, NetMonster shows you something most phones hide.

You can tell whether NSA is genuinely in use or merely deployed in the background. The app also reports carrier aggregation across combined 4G+5G NSA bands, so you understand exactly how your device builds its connection.

Who Should Use NetMonster

NetMonster serves a wide range of users:

• Network enthusiasts who want raw data on every tower nearby
• Travellers who map coverage and dead zones
• Android developers who test app behaviour on weak connections
• Field technicians who diagnose signal problems
• Anyone curious about what their phone connects to all day

Why NetMonster Stands Out

NetMonster pairs deep technical detail with clear explanations. It reads tower identifiers, logs every active connection, maps and filters results, exports data, and visualises signal changes in real time.

Its coverage spans GSM through 5G SA, and it goes beyond the basics by detecting LTE-Advanced carrier aggregation and distinguishing deployed 5G NSA from active 5G NSA.
