I was using Player FM for many years before switching to Pocket Casts because so people were raving about it and Player FM went effectively paid-for. I’ve honestly been rather disappointed by Pocket Casts, the interface is not very intuitive and the auto-downloading options aren’t very good. Can’t really complain as a free app though. The Spotify interface is even worse, so I won’t use that despite being a subscriber.
It may be too much to expect a good podcast app for free, I just wish there was a reliable one with a one-time fee, rather than a subscription model which seems to be the way these things go once an app becomes popular enough. I’ll have to try some of the other suggestions in this thread.
