Designed to overcome some of the limitations of the official NPR app, the Public Radio Player app caches news stories you want to listen to on WIFI (by default) so that no matter where you are, you can listen to them without burning your mobile data. Unlike the official app, this app has no advertisements!
Public Radio Player has Chromecast integration, so you can stream your stories to the TV.
As a work in progress (and love), please contact me with features you would like to see added. Thanks!
