I know this is boring, but I tend to just use Apple Podcasts. I don’t really have any issues with it. The only thing I’d like to do is be able to set different speeds for specific podcasts.
I did start switching to Overcast which does have that option. It’s also OK but I’m not convinced it is otherwise a big improvement on Apple Podcasts. I also tried Downcast which I didn’t really get on with.
I think I just use podcasts differently to everyone else. These apps all seem to be about setting up playlists and having a constant stream of things. Whereas I just like to have a look at what episodes there are and play one that I want to listen to. I think the layout of Apple Podcasts just works better for me.
I’ve not tried Castro yet.
I just think there are only so many features I really need. Maybe I’m just simple.
