I recommend posting in the forum for the operating system of interest (Android Gospel Library, BlackBerry Gospel Library, iPhone/iPad Gospel Library, WebOS Gospel Library, Windows Mobile Gospel Library). Each system is in different levels of development for application. The one with the most features due to a significant head start in development is the iPhone/iPad Gospel Library.
