I use the podcast app very frequently across iPad/Phone/MBP and never have had a problem. What problem/s are you having?
It stops playing out of the blue, I tap play again and it works for a few seconds and the voice starts distorting to the point I can't even understand a word. I rebooted, deleted the app and reinstalled it, still get that problem almost every day. (iPhone 5 32 gb - latest iOS)
