App Description
Castro is a beautiful, full-featured podcast player that makes it easy to track and manage lots of podcasts at the same time. Only listen to the episodes you want and easily skip the rest, queue up hours of podcasts at a time and enjoy a seamless listening experience with carplay compatibility, chapter support, trim silence and much, much more!
HOW IT WORKS
1. New episodes land in the NEW tab. Read their descriptions, add episodes you like to your QUEUE, and clear the rest.
2. Press play to listen to episodes from your QUEUE in order. Queued episodes are downloaded automatically.
3. Re-order your QUEUE to plan your next few hours of listening at any time. Browse your LIBRARY to review the back catalogue, quickly access starred shows, and see your listening history.
Subscribing to a podcast is no longer a commitment to listen to every episode. You don’t have to manage a huge list of subscriptions or choose a few shows and miss the rest.
