A basic port knocker client for Android. Similar to the other port knocker apps but with a nicer interface. Includes a widget and the ability to choose an application to launch after knocking. The media/storage permission is needed for the import/export feature which allows you to save your list of hosts and then load them later.
Please don't hesitate to contact me if you encounter any bugs, or even if you just have suggestions.
