If you're looking for a free, hyper-functional podcast app that will search _thousands of RSS feeds_, allow me to introduce [PodcastAddict](https://play.google.com/store/apps/details?id=com.bambuna.po...). I've been using it for some time now, and every day I discover something new to enjoy. It's indisputably the best podcast app for Android, and it's leagues beyond iOS's native app.
