A free program for Android, by Ian Hawkins.

The free and open-source app, WiFi Tracker, is designed to be a simple and useful tool that allows you to see the state of wireless networks in your area. It is a combination of a map and a list, where you can select which access points you want to see.

This tool can be used by anybody, even if they don’t have any technical background. It is especially useful for people that want to explore the Internet, as it provides a good overview of the Internet’s infrastructure.
