A multiple station app is simply a single app with multiple stations available within it. Perhaps you have a cluster of stations in a market that you want to brand under one app, or a station with an HD2 or online side-channel you wish to make available in a single app. Your app can open up and be fully branded as "WXYZ" but through a menu option, allow users to switch to "WXYZ-HD2" and experience that station without switching to another app. Download the KXOJ app for an example of a multi-station app.
