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 :)
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.
