Do you have an iPod Touch at least? I think it will work on there too. Anyway here are the list of features:
It has podcasts, videos, daily devotions, information about the WELS, Q&A, a 3-year Bible reading plan, Call Report (which from what I can tell by the app is for teachers and staff ministers), and Together, which seems to be a news section.
Now the devotionals are available in audio or text format, which is really handy because you may not always have your ear buds or speaker system nearby or it may not be convenient to listen to audio at that time. The podcast is of course audio only and that's the WELSTech podcast which discusses how technology can be used to aid the work of the church. The Through My Bible in 3 Years can be listened to as audio or read. It's really a well put together app and since it's free I consider it an essential, if your phone can support it. Is this enough of a reason to go out and buy an iPod Touch, iPhone 3GS or 4, an iPad or an Android device? Possibly.
