I love podcasts and use overcast every day. It's almost always 'invisible' (I press play and it just works) but I find the way I can have my 'every episode' podcasts and the ones I just dip into easily discoverable in the app.
I'm a paying user of Overcast since the very beginning. Happy to support indie devs like Marco Arment. And it's just a better podcast app than Apple's :)
This is my favorite podcast app hands down! The ability to create your own lists of podcasts makes it easy to binge and consume content any way you want. Also, very easy to search for and add new podcasts without leaving app.
