Podcast Source is a free iPhone app developed by Wizzard Software that allows you to conveniently access all your favorite Libsyn shows in one location. With this app, you can add your preferred podcasts to your My Shows tab, whether you have just one favorite or multiple shows you enjoy.

The app provides a range of features for each show, including downloadable wallpapers for your iPhone or iPod Touch, access to exclusive bonus content, the ability to call the show directly from your iPhone, and the option to email the show with your questions and comments. You can also follow the show on Twitter for updates and stream episodes from anywhere.

Podcast Source ensures you're always up to date with the latest episodes, with an archived back catalog available as well. You can download episodes to listen to offline and enjoy playback resume if interrupted by a call or other distractions. The app also offers a favorites feature, allowing you to mark episodes you want to return to. Additionally, it provides quick access to all the contact methods for each show.

Please note that not all features are available for all episodes, and the call-in feature is exclusive to iPhone users and not available for iPod Touch users.
