I know, I know, using Google apps isn’t the best, but this was a perfectly good Podcast app with all the features you might want.
Apparently they’re moving everything over to YouTube Music, where a lot of the features of Google Podcasts aren’t implemented yet.

One of the best apps on any platform
I’m kind of into Podscast Addict. Not sure how it compares, but its pretty good.
It’s not open source
