Fool friends and family with this app that makes it look as though you're hacking into their Wi-Fi.
One of the best prank Wi-Fi hacking apps, this makes it look as though you can get the password to anybody's WiFi. It doesn't actually give you the real password, but your friends's don't know that!
Funny prank and easy to use.
Database of open WiFi networks.
Instabridge is a great tool for finding free WiFi. You can add networks you connect to, either to share with everyone, just your friends, or save them just for yourself. Connecting to networks that people have shared the password to from places such as hotels seems like a moral and legal grey area to me however.
