WiFi - a Very entertaining application which will help you to find free wi-fi in your city. How it works, all you need is to connect wifi and if it does not contain a password, it is automatically saved this app and share these data with other users. That is, the system works so that users worldwide can share data with each other, thereby forming one common network that has many access points, of course some of them may stop working, and then eventually it will disappear from the map.
