Coverage Mapper is a crowd sourced cellular signal strength mapping application.

Coverage Mapper will record and submit cellular signal strength data to a central server, to generate accurate coverage maps for your provider.

Please check out the website (, preferably on a computer, to get a better understanding of the application before downloading it.

As you travel with the application running, it records your device's signal strength, tied to your current location. This data is all uploaded to a central server, where it is aggregated with the data from other users, and averaged into accurate coverage maps that show not just where a provider has coverage, but also how good the coverage is.

This is a beta application. Please report any issues on the forum or by email.

Since this question is frequently asked, install to SD is not an option, because Coverage Mapper runs as a background service, which cannot be moved to the SD card.

    The concept behind this is brilliant - capture a user's mobile device signal strength and display it on a map to give other users Real World coverage maps... But in practice, this depends largely on where you reside - Australia for example, has very little data. There is also a few design quirks - for example, the guide to the colors is only on an external Web site, the screen must be left on and
