This app allows you to check which outgoing UDP ports are open on your network.

You can use it to find out if your Internet connection is secure and to check if the remote service you are trying to reach is open.

How does it work?

If you are using a mobile device to browse the Internet, it will not work properly unless you allow it to use the internet. This is because the app needs to be able to send data to our server in order for it to work properly.

When you allow the app to use the internet, it will start monitoring the ports for you. If it receives a reply, it will show the port on the list.
