I use Podbean coupled with Pocket Casts. They do everything I need. These apps are really useful.

Also, there are only so many things that you expect from a Podcast app-

- Does not have ads. (Some banner ads are okay) - Offers download in external storage - Has bookmarking capabilities - Offers all the titles I listen to - Saves data associated with an email address

There. Simple. Don't want anything more.
