Have you tried gpodder? It basically does what it says on the tin it plays podcasts (and you can subscribe to them etc.) and if you have gpodder on desktop and a gpodder compatible app (like AntennaPod) on you phone it will not only sync over your subscriptions but even you listening status, so you can just pick up where you left off.

Honestly I just use AntennaPod on Android. I’ve used Gpodder Desktop before but I don’t really listen to podcasts on desktop… So I don’t really need the sync but it’s nice to have especially if you’re moving phones/OS

Regarding AntennaPod it’s honestly the perfect podcast app it does everything (chapters/chapter images …) I want from a podcast app and it’s open source

My selfhosted Nextcloud does:

• Cloud storage (including photo storage)
• Contact/Calendar/Task Sync (DAV Droid)
• Notes
• Podcast subscription and progress sync (gpodder)

While I use OSMAnd for offline navigation MAPS is still my go-to for navigation/discovering places.

My phone is currently running stock Android
