Try AntennaPod.
I don't have a cell phone. And it wouldn't make any sense to setup Android Studio just to listen to a few podcasts.
RSS feeds are great.
Honestly, I don't listen to enough podcasts to justify using an RSS reader. Most podcasters have not figured out that they are entertainers first-and-foremost, so most podcasts are a chore to listen to. But, I give an exception to my friends, because I'm more interested in keeping up with them than being entertained.
