For Android users, I highly recommend Podcast Addict, which also seems to be the work of a single dev. It's incredibly good and constantly getting new features.
Can't reccomend it highly enough, for a long time it was my go to RSS reader too.
What is your RSS reader now?
Is it that better than the official Google Podcast app? I have been using it for years and it's pretty nice.
Yes
The good third party apps are leaps better than the platform official apps. The developers are passionate and the platform apps seem unwilling to risk adding too many features.
