Even with a number of workable free services for listening to podcasts, Pocket Casts is a popular option for episodic audio. Indeed, it does cost you a few dollars, but the app is well designed and offers a more comprehensive feature set that some of the free software doesn't. Following its sale, in May, to a public radio group that includes NPR, Pocket Casts is debuting a big overhaul today that makes what many consider to be the best podcast repository even better. The UI will feel somewhat familiar, but you'll notice that a few things have been tidied up. Specifically, the individual podcast episode lists and the player interface were where the tweaks stood out to me the most -- with changes to color, icons and layout. However, everything you need to use regularly is still easy to find.
