I bought a new app for my iPod Touch. It is called "Downcast". The app basically plays podcasts. Small audio shows. This has been on my wish list for sometime as I've seen it recommended at Macworld.
In the past, I've attempted to use Apple's own "Podcast" app and for a long while I was using Sticher. But I find Downcast to be cleaner, intuitive and simpler. The audio quality seems better too, but that maybe wishful thinking. I like how the volume control is easily available when listening to a show. I like the ease of putting together several podcast playlists.
Downcast is an app that I would recommend. It is only $1.99 and it is available in the App Store.
