Castro announced a deep integration between Siri and Castro that shortens the distance between you and your podcasts.

What’s your favorite show? Ask Siri to play it in Castro, and we’ll do all the thinking for you. If the show is already in your queue, we’ll play the episode closest to the top of the list. If we can’t find an episode in the queue, we’ll check the inbox. Even if you’re not subscribed to the show, we’ll go find it and play the latest episode for you. You can even ask Siri to play the first, or the newest episode and Castro will skip episodes you’ve already listened to.

There are a total of 30 requests that you can make of Castro through Siri. Casto knows that it can be hard to remember them all, so they made a hand reference guide in Settings → Siri where you can find what you’re looking for to make your day a little easier.

Castro also added shortcuts for Castro that were built to connect Castro to other apps. Search Castro’s directory to get access to data from any show or episode. You can also add items to your queue.

9to5Mac reported that the Castro Podcast Player of iPhone and Apple Watch now offers support for a variety of Siri commands to play shows, play a certain genre, or even the news. You can also use Siri to control playback controls including Chapter skipping and Trim Silence.

Castro describes itself as “an app for today’s broad-minded podcast enthusiast”. It is an app that is available for download on the App Store. (It does not appear that Castro is available for Android). Castro wants to help podcasters grow their audience where they are already listening by promoting their podcast on Castro.

There are three options for podcasters who want to grow their audience in Castro:

7 Day Promotion:

•  $99 USD
• Displayed in all categories
• 12.5K to 15K impressions*

15 Day Promotion:

•  $199 USD
• Displayed in all categories
• 25K to 32K impressions*

30 Day Promotion:

•  $399 USD
• Displayed in all categories
• 50K to 64K impressions*

The asterisk connects to a portion of Castro’s Terms of Sale information. It says: “Estimated performance of promotions are updated from time to time based on current promotion performance, your promotion performance may vary. Impression rates vary over time, and subscription rates are affected by the perceived value of your podcast.”

Other parts of Castro’s Term of Service include:

Once you purchase a promotion, it must be approved by Castro before it goes live, which typically occurs within 1 business day when inventory is available. Castro reserves the right to reject a promotion for any reason, such as (but not limited to) billing issues, quality concerns, or content.

If your promotion is not accepted, your payment will be refunded if possible, with the refund pro-rated if the ad has already run for a portion of its purchased duration.

All sales are final. No refunds.

I was unable to find any more details about what else Castro may be offering podcasters who want to grow their podcast on Castro. I’m also unclear on how Castro intends to make it clear to podcasters how many impressions they received. Those who wish to purchase a promotion plan must click on a link on the Castro website and fill out a two page form with their information.
