When creating a new application on the dashboard, you're given two different tokens, beta and live. These two tokens count for one application rather than two, however. The different tokens can't be used on different applications on different platforms due to the varying information sent from each platform.

If you have two native versions of your application, one for Android and one for iOS, two separate applications on the dashboard will be required.  

You can add a new application from the dashboard using the application selection drop-down on the top-left corner.
