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.

* Drag and drop support helps you triage and reorder your queue.
* Castro sports an elegant dark mode (requires Castro Plus) and well-thought out sleep timer, offering the best in night time podcast listening.
* Our servers constantly scan for new episodes across every podcast, so your phone doesn’t have to, saving battery life and data usage.
* Queued episodes are automatically downloaded, so you can focus on deciding what you want to hear and let Castro manage the details.
* Beautifully rendered full screen show notes.
* Episode notifications include a short summary of the episode to help you decide if it interests you. You can play, queue or archive the episode directly from the notification without opening the app.
* CarPlay support.
* Watch app to control playback and select another episode from your queue.
* Full play history.
* Star episodes to easily find your favorite episodes later.

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.
+ Trim Silence — With this option on, the app will analyze audio as it plays to detect silent parts and accelerate those parts. Get through more episodes faster.
+ Enhance Voices improves the listening experience for many podcasts and makes it easier to hear in loud environments. Under the hood, Enhance Voices applies a dynamic compressor and a peak limiter to increase volume just where it’s needed.
+ Mono-Mix — Mixes a stereo podcast to mono, which makes it easier to hear podcasts that pan some guests on left/right channels.
+ Chapter skipping and selection.
+ Chapter and episode artwork.
+ Episode Limit lets users specify what number of episodes of each podcast to keep.
+ Set a start position for episodes of each podcast.
+ Customize settings per-podcast: Episode Limit, Trim Silence, Enhance Voices, Mono Mix, Skip Intros, Playback Speed.

Castro Plus costs $8.99 per year or $2.99 per quarter. Prices are in US dollars and may vary in countries other than the US.

Castro Plus is charged to your iTunes Account at confirmation of purchase. It will renew on the day before the current subscription period ends. You can cancel auto-renewal any time from the Castro settings screen.

You can switch between the two subscription periods after you pick one, but your trial period will end immediately if you do, so it's best to wait till your free week is over before changing.

Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. Your account will be charged for renewal within 24-hours prior to the end of the current period. Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable.

Editors' Notes

The only issue we have with podcasts today? Keeping track of all of the good stuff. Castro acts as our podcast personal assistant. Once we’d rifled through the app’s vast (and we mean vast) offering, Castro helped us prioritise and organise what we wanted to hear—and clear our in-tray by deleting them once we’d listened.

Great podcast app

Donald Trąba

Has maybe one or two nuisances in UI, but overall it fits the bill perfectly and is my favorite podcast app.

About nuisances: it should be easier to access episode details - this info is main driver to decide whether new episode should be queued or archived. The other one is minor.

I am disappointed - rozczarowany


The developer site is misleading. Before buying I made some research if it has all features I am looking for. I found on the developer website that indeed it has. After installation it turned out the information are about older version of the app and most of the features are not present in Castro 2.

Zanim kupiłem aplikację to sprawdziłem, czy ma wszystkie funkcje, których szukam. Bezpośrednio na stronie dewelopera były ładnie opisanie. Niestety - okazało się, że to funkcje starej wersji aplikacji i nie ma ich w nowej wersji. Nie jest to w żaden sposób zaznaczone na ich stronie.
