This looks really well done. I don't think the messaging is strong enough to get me to switch from PocketCasts so you might want to work on that. I suspect podcast listening is a habit for most people and will just use what they always have. Every few months, a friend will get tired of apple podcasts and ask for an app recommendation, but people don't take switching lightly.

Can I import my subs? Who will see my comments? do my friends have to use repod? etc
