Tunemark Radio is an internet radio tuner app for the iPhone and iPad. Listen to thousands of different radio stations or manually add a station. It is nice that there are no banner ads. I particularly like the fact that you can pause and rewind while you are listening. You can select a background that suits your taste or add a custom background. App continues to play in the background while you use your device. Normally $0.99, it is free for downloading for a limited time.
