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
