About this app

This app will be constantly developed and improved. There are still many features missing, which are replenished over time. In case of crashes please press the feedback button. The developer likes to receive requests for new functions by e-mail.

If the displayed values doesn't seem to be correct, please try different api settings for each value. You will find them in the calibration settings.

With G-MoN Pro, all available cell data and measured values in 5G NSA and SA, 4G, 3G and 2G mobile networks can be clearly displayed and graphically displayed. The details of this data depend on the smartphone manufacturer and the Android version.

You can log all cell data and measurements in a csv and kml file, even with screen off. Dual SIM is fully supported. The kml file can directly be loaded into Google Earth if it is installed on the phone. The logged rx levels are displayed im realtime in the map.

The new cell list file format clf v4 is supported. Please follow the link below for details:

The Cell Compass always points to the Best Server cell when moving (GPS) if it is included in the CLF. With a tap on the arrow, the seat direction can be changed to the direction of travel, e.g. when you sit in a train. In addition to the direction, the distance to the cell as well as the current speed and the GSM accuracy are displayed.

Dual sim phones are supported. In the overview tab you can quickly switch between the two active SIM cards with a tap of the network and cell data.

Ratings and reviews

Excellent app although in a beta release. The suite of available API for radio measurements overcomes a few compatibility problems I had experienced with the still valuable G-MON app with some latest devices. I'm definitely looking forward to using the log function and kml generation also in G-Mon Pro! Super.

Why is it asking for permissions to make phone calls ? Nothing explains it during installation, but location and something else are described in a pop up. Nice app.

Excellent. Very useful and easy to use. Cell file makes identifying sites a doddle.. logging capabilty very good. Easy to import to Mapinfo...
