I use the TuneIn Radio app on my iPhone to listen to SWR4 Tubingen, a German radio station in Baden-Wurtemberg. It is also available on the internet. I'm studying German language, using Duolingo and Rosetta Stone. I can read and understand German very well now, but listening to the radio helps me with listening and understanding. I also get to speak with a German lady at a local Burger King about once a week, and she is very helpful with a lot of the grammatical rules.
