You don't necessarily need one for each site. Although not Free($3.99) , My favorite has been Pocket Casts https://play.google.com/store/apps/d...ly.pocketcasts But, it's been a little while since I last used it. If I was to ever go back to a podcasting app/site, this wins hands down, for me at least. I am sure there are others which are FREE, probably better but this is the one I like most. I like that you can use it in conjunction with your peripheral.
