Just gave it a shot, and I wasn't impressed in the least. These types of apps are where Apple really fails. It's like they don't use the same designers they do for any of their other products on these small apps.

The interface is lousy, and very similar to the Music app. Discovery doesn't seem very useful either.

This might be useful for a 'light-weight' user and listener of podcasts but this doesn't even come close to apps like Downcast in terms of features.
