I'm using Google's but I don't really like it.
EDIT: is there anything that can sync with a linux podcast app (desktop)?
I used to use AntennaPod a few years ago, not sure what it's like now but it looks to still be updated. Nice app as it has built-in search, etc. rather than just taking RSS feeds.
Another endorsement for AntennaPod, I also use it every single day. No issues with podcast length over here.
Podverse! I'm pretty sure it's the only FLOSS app that has implemented all the podcasting 2.0 features. The only thing it's missing is Android Auto :(
There is a bounty out to get andriod auto support. I use and love podverse
AntennaPod is a good one. Personally I use podcastaddict solely because it has casting and I put podcasts on my TV.
I use AntennaPod but don't love it. It can be quite buggy. Podcast length is never correct for example and will reach the end before the podcast has finished.
I use podverse and love it. the other foss setup I have used is antennapod and kasts synced with the gpodder plugin for nextcloud, but kasts was kinda buggy so I switched to podverse
