For Android devices, we hear the best feedback about Podcast Addict.
For iOS, many have tried various Apps but they typically come back to the built-in Podcast App for iOS. It seems to be the most stable App.
However it’s difficult to find the DNR Live Streaming Show in the iOS 11 Podcast App. The quickest way: Go to the bottom of the App, click Library, choose DNR 2.0, scroll all the way to the bottom of the feed and then choose “Available Episodes” and then “DNR LIVE STREAMING SHOW” should be at the top! Unfortunately you may have to repeat these steps the next time you open the app.
