I'm not entirely sure what this does. According to the site, it "shares WiFi". I don't know if that means it'll send the WiFi credentials to all of your devices over Bluetooth or an app or create an ad-hoc network. It would be helpful if the website had screenshots or drawings explaining exactly what GetWifi does.
