Cellular Signal Analysis And Reporting Tools

Version 2 of our app is now available to the public for download.

Get it on Google Play

This app will survey mobile phone signal data, and with a paid Mastdata licence can also locate existing masts and other infrastructure in the UK. It is suitable for both private and commercial use.


If you are taking a journey by foot, bicycle, car, rail or ferry you can identify signal strength and coverage along your route using the Mastdata app. You can even watch the results of the survey appearing live as you travel. You can always view survey results and mobile coverage data collected on your device even if you don't have a login. Take the journey, collect the data, and then using the app, you can go back and see the results collected by your device.

Benefits Include:
  • Viewing potential coverage in a new area if you are looking to move home or office
  • Identifying a suitable alternative where fibre broadband is not available
  • Potential coverage for future outdoor events/activities

With a login, you can view the data you collected across multiple devices. This would be useful if you ever reinstalled the app or upgraded your phone and wanted to keep your data available.


If you would like to use the additional tools that we have to offer and don’t yet have an account with us then it’s easy to set one up and subscribe. With a paid account, viewing what's around you is popular, so your own postcode could be an initial search.
