outSSIDer is extremely simply and useful. It does everything automatically, in fact you'll only have to click one button to start, stop or resume the process.
It consumes very few resources and detects networks really fast. Find new connections, check signal level and enjoy the Internet anywhere, because WiFi is important.
If you usually need to find new networks when you go out, outSSIDer can be very helpful.
No limitations, buy it in case you want to contribute.
