I use the free version of Podkicker, a free podcast player for Android every day so when I saw there was a pro version I immediately bought it.
It has a vastly different UI and it somehow detected my original Podkicker subscriptions (I presume from the cloud?) but did not detect my already downloaded podcasts so it looks like I’ll be using the free version for a while. The UI will take some getting used to too as it’s so different but I wanted to support the author as I like the free version so much. Here’s a great review of the pro version if you’re interested.
