The PATLink Android app is a handy tool to facilitate the testing process of a mechanical keyway and is used as a replacement for the desktop application. The application is compatible with Android devices and allows users to scan QR codes and bar codes to get information about the previous results, the test status, and the previously used test sequence.

In order to activate the tool, users need to purchase the activation code from their local supplier. Once they have done that, they can start using the tool and it will work for them as long as they have an internet connection.
