One of the biggest changes introduced in Pocket Casts 5.0 is native resolution support for the bigger screens of the iPhone 6 and the iPhone 6 Plus.
And on iPhone, whether on a new bigger-screened one or not, the app's Now Playing screen has been enhanced with several upgrades. As noted by Pocket Casts developer ShiftyJelly:
Mark as played from your Up Next list. Tap an episode in Up Next to play it now, pushing your current episode down. Double tap with two fingers to quickly skip past boring bits. Your favorite sleep time is now saved.
Pocket Casts 5.0 also adds support for setting notifications on a per-podcast basis. And speaking of notifications, the update also enables interactive notifications on iOS 8, allowing you to add a podcast to your Up Next list or download it right from a push notification.
Furthermore, the update features a revamped interface that's more in line with iOS 8, support for automatic downloading of new episodes, and other improvements.
Pocket Casts is featured as an “essential app” in AppAdvice’s Podcast Apps AppGuide.
