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.

What's New

Version 3.0.3

* Fixes an issue where audio would appear to play in the interface but not actually be playing. This would usually occur after an audio routing change (e.g. connecting / disconnecting lightning-jack earphones).
* Invalid audio files appeared to play but no sound comes out. Castro will now display an error if it can’t play a file.
* Fixes a bug where an incorrect play progress position could get stored, which would cause various problems such as: podcasts resuming playback in the wrong place, episodes archiving from the queue unexpectedly.
* Skipping forward or back arbitrary amounts using Siri was always jumping by the app’s skip interval instead of the amount requested to Siri.
* “Archive All” confirmation text in dark mode was the wrong colour.
* Unsubscribing from a podcast now deletes our artwork cache. (It’s now possible to force an artwork refresh by unsubscribing and resubscribing to a podcast.)
* Fixed dragging to re-order the queue in iOS 10.
* Fixes issues where incorrect chapter/episode artwork could be shown in the player.
* The “confirm streaming over cellular” warning is shown/spoken if you press play manually, not only when continuous play would start it.
* castro://play and castro://pause URL schemes now work
* Fixes a crash that could happen when seeking in an invalid episode. This led to a crash loop for some users.
* Our servers are now better at selecting the audio enclosure in an RSS feed when multiple options are included; they’re also stricter at rejecting episodes that don’t include an audio enclosure.
* Made background continuous play transitions between episodes more reliable.

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 prioritize and organize what we wanted to hear—and clear our in-tray by deleting them once we’d listened.

Wo bleibt die iPad-Version?

Nihilistisches Abhörkommando

Eigentlich mag ich Castro und ich wäre durchaus bereit, die Miete für die Pro-Version zu zahlen. Aber solange ich meine Podcasts in zwei unterschiedlichen Apps verwalten muss, ist es mir den Preis nicht wert. Ich verstehe auch nicht, wie man in Zeiten von Auto-Layout das iPad so konsequent über Jahre ignorieren kann.

An die suboptimale Einhandbedienung nach dem Sprung auf Version 2 habe ich mich ja langsam gewöhnt, leider hat sich hier mit Version 3 nicht viel getan. Am nervigsten ist, dass man die Episodendetails nur über den kleinen Pfeil am rechten Rand erreicht. Hier wäre eine Geste praktisch. Seltsam finde ich auch, dass der Player weiterhin zweigeteilt ist. Entweder bekomme ich die Controls zu Gesicht oder die Beschreibung der aktuell laufenden Episode. Ein direkter, intuitiver Wechsel (zum Beispiel durch Tipp auf den Titel) ist nicht möglich. KORREKTUR: Es gibt eine Wischgeste nach Rechts, um im Player die Shownotes sehen zu können, immerhin. ;)

Das Update fühlt sich eher an wie v2.5, aber da würde vielen dann wohl das Abo aufstoßen. Leider ist nicht klar, was man langfristig für das Abo bekommt. Bei Ulysses gibt's zum Beispiel das Versprechen der Weiterentwicklung mit Einblick in die Pläne. Die derzeitigen Pro-Features rechtfertigen meiner Ansicht nach eher einen einmaligen In-App-Kauf. Für eine Mietgebühr erwarte ich schon dauerhafte Leistungen.

Effectiveness and enjoyment 100%

großes E

Klasse Konzept. Sehr durchdacht. Tolle Umsetzung in Handhabbarkeit und Style. Mich überzeugt Maß und Mittel der Einflussmöglichkeit auf potentiellen Konsum einströmender Folgen von abonnierten Podcasts. Neue Folgen landen in der Inbox und man entscheidet mündig und proaktiv, ob man die Folge seiner Playlist/Queue zufügen mag, oder derzeit nicht. Falls aktuell nicht, kann man später jedoch getrost auf das Archiv zurückgreifen und die vorerst abgewählte Folge in eine jetzt thematisch passend generierte Warteschlange/Playlist hinzufügen. Inbox Zero. Effectiveness and enjoyment 100%. In der Bedienbarkeit und inneren Logik wirklich klasse! Eine App die ich gerne fördere und zugehörige Arbeit und eingebrachte Leidenschaft durch Bezahlung wertschätze.
