NetMonster

NetMonster is a fast network monitoring tool for Android. Install the latest free version to gather, view, and save key details about nearby cell towers. It’s built to help you understand your current mobile signal conditions, test optimized connections, and take advantage of a wide range of customization options.

Outstanding Features

Collect, display, and store tower data

NetMonster continuously gathers information about nearby cell towers and records it for you. Each tower has its own identifier, and the app shows you that ID. In some countries and regions, it can also retrieve more accurate location details for the towers.

Continuous logging while the app is open

As long as NetMonster is running, all cell towers your phone connects to are logged. When you close the app, logging stops. You can also:

• Edit tower locations manually
• Browse towers on a map
• Filter the list of cell towers
• Export all recorded data

Signal visualization and measurement explanations

NetMonster can display how signal conditions change over time, and it includes short descriptions to clarify what each measurement means and how it may impact reception quality or even theoretical maximum speed.

Supported mobile network types

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

For LTE, NetMonster can also detect aggregated carriers (LTE-Advanced). In areas where 5G NSA is available, you can tell whether an NSA connection is currently active or has only recently been deployed. It also supports viewing carrier aggregation that involves 4G + 5G NSA (4G+5G NSA).

• Detailed base station info, including connection type, frequency, speed, operator, and more
• Tower distribution map
• Real-time signal charts for RSSI, Ec/No, and RSCP

Wonderful Benefits

• Record base station details for the network your phone is currently using

• Post-process recorded data to help import additional information for nearby/adjacent cells



• Download precise transmitter location data for supported countries and regions
• Manually upload data to the location management system

Excellent Performance

Serving cell detection in emergency mode

NetMonster can scan and detect serving cells even when Android is in “emergency call only” mode. This means you can still collect, view, and record cell data at any time as an Android user.

Save your phone’s connection logs

Use NetMonster to capture important base station information and store it on your device. You can review saved results whenever you want. The app also includes customization options such as changing your device location and browsing base station lists on a map.

Visualized signal changes and measurement methods

To make scanned cell data easier to analyze, NetMonster offers signal-change visualization. Track signal behavior in real time and, when needed, read explanations for key measurement results.

Summary

With NetMonster, your Android network connection becomes easier to understand. The app can also help you improve performance and confirm your network is working as expected. It provides practical information to support smarter decisions—whether you’re trying to find the best spot for calls or internet access, or troubleshoot possible network issues.
