I think this is a great idea and I've happily subscribed. I'm waiting on the Android Version of the app of course.
One thing though, will the app have the ability to save the podcasts to the app and make available offline? I mostly listen to podcasts while I am out of the house and in Canada cell providors charge a lot of of money for not a lot of data. It'd be awesome if there is a "make available offline" feature like streaming audoio services like spotify, Rdio, Apple Music, etc.
