Free Zone will not hack WiFi networks nor will it attempt to bypass their passwords. Instead, you will be automatically connected to one of the increasingly common public networks, or told exactly where the nearest one is so you can connect to it easily.
Among the options available is the chance to be notified by a vibration or a sound every time you're near a WiFi network that you can connect to.
Free Zone is a very useful tool, particularly targeting those users without a 3G connection on their mobile phone. It can also come in very handy to Android tablet owners who want to stay connected for as long as possible.
