Look for the best iPhone apps or best iPad apps to keep up with your favorite podcasts? Depending on who you ask, podcasts are either fringe media for geeks, the future of radio and television, or something in between. Apple embraced them years ago, providing an entire section in iTunes dedicated to making podcasts easy to find and easy to follow. They also created the iPod, and then the iPhone, and the iPad, making it just as easy to listen and watch podcasts anywhere and everywhere you go. Whether you're trying to get our podcasts — iMore show, Debug, Iterate, Review, or Vector — or any of the other great internet shows, the most important question is what podcast app should you use?
