App Store Description

Castro lets you track lots of podcasts at once without getting overwhelmed. Here’s how it works:

  1. Newly published episodes land in the Inbox. Read the descriptions, queue the good ones and archive the rest.
  2. The Queue is a central playlist where you organize your next few hours of listening. Queued episodes are automatically downloaded.
  3. Press Play. Castro plays your queue in order from top to bottom. Reorder or archive queued episodes anytime.
  4. In the Archive you can find the back catalogue of all shows you subscribe to, browse your listening history, and easily access your starred episodes.

This triage flow lets you expand your listening habits without getting overwhelmed. With Castro, subscribing to a podcast doesn’t mean making a commitment to listen to every episode. You don’t have to choose a few shows and miss out on the rest.


Castro Plus is an optional subscription to unlock a range of advanced features. There are quarterly and yearly payment options, and both include a one week trial.
