Advanced mobile network analyzer app for accurate cell tower tracking and 5G coverage insights

NetMonster is a powerful tool that collects, displays and stores detailed information about nearby cell towers. Every tower includes a unique set of identifiers, and NetMonster shows them clearly — with precise tower locations available in select regions. This makes it ideal for users seeking a reliable cell tower tracking app, a 5G coverage mapping tool, or a comprehensive cell signal strength monitor.

The app continuously logs all cells your phone connects to until you close it. You can edit tower locations, browse them on an interactive map, filter results and export your full dataset. NetMonster also visualises signal changes and explains what each measurement means for reception quality and theoretical maximum speeds, making it a dependable mobile network analyzer app for both beginners and experts.

Supported networks include GSM, CDMA, WCDMA, TD-SCDMA, 4G LTE, 5G NSA and 5G SA. NetMonster detects LTE carrier aggregation (LTE-Advanced) and shows whether 5G NSA is active or only deployed, including 4G+5G NSA aggregation where available. Built on the open-source NetMonster Core library, the app offers transparency and accuracy enthusiasts can trust.
