Apple is designing its services to optimize them in the new iOS 6. Now was the time Apple to have an application dedicated to podcasts and videocasts.
Podcasts app is the easiest way to find, sign and play your favorite podcasts on an iPhone, iPad and iPod touch. Allows you to explore the hundreds of thousands of audio and video podcasts that are available in free catalog podcasts, and play the most popular podcasts, organized by topic via the brand new Top of stations.
The new application allows other user experience. By placing a single application to your audio and video podcasts Apple maximizes the utilization of this resource. This way you can explore hundreds of thousands of podcasts, including programs available in over 40 languages.
