New in Castro: Top Picks

Introducing Top Picks

When you have a lot of podcasts in your library, it can be a challenge to scan through all of the new episodes and decide what to play to next. All too often, the episodes you really want to hear can get lost in the stream of new shows.

Top Picks Hero image

Top Picks is a new feature in Castro that solves this problem. It uses your previous listening activity to surface the new episodes of podcasts you’re subscribed to that you’re most likely to want to hear.

So how does it work? Just tap Top Picks to see your recommended shows, and add them to your queue with drag and drop, or a couple of taps.

Simple, Powerful, and Private

The best part? Because Top Picks learns from your listening history, you don’t need to do anything to set it up. All of this analysis happens on your iPhone, using local data, so it’s 100% private.

With Top Picks in Castro, you can subscribe to hundreds of shows without having to worry about missing the best episodes. Your picks will get even better over time, just by playing more shows you like.

From the start, we designed Castro for listeners who want to enjoy a wide range of podcasts, not just the same voices over and over. Now, with Top Picks, Castro is the only podcast app that lends a hand with the central task of picking the best new episodes to play.

New: Enhanced Podcast Discovery, Snappy Search, and more

Hot on the heels of January’s update (which added added local search), this year’s second big Castro update is now available in the App Store. In this release we revamped the Discover tab, dramatically improved podcast search, and re-thought the way we talk about features in the app.

Revamped Podcast Discovery

We designed the new Discover tab to offer a quick, simple way for us to highlight a handful of interesting podcasts each week. The new, Instagram-like feed makes it easy to quickly scan for interesting collections. These collections are curated by us, and we will introduce new collections weekly. It’s designed to be a relaxed way to find interesting shows and know what’s new, not a deep dive into a directory of every podcast anyone might ever want.

The tab still includes the per-country category lists, but we’ve reworked them to fit into the feed. We’ve selected a single great show to represent each podcast category.

Snappy Search

This update also brings a redesigned search that instantly returns results as you type. This took a lot of work on the server side, but the bottom line is that search in Castro is now much faster, and far more accurate.

It’s also much easier to subscribe straight from a search result, just by tapping the + next to the search result.

Easier to Learn

When we originally designed Castro we borrowed terminology from email, to-do, and other productivity apps to describe the “triage” flow of managing episodes in the app. This language worked well for users comfortable with those apps, but it made Castro a little harder to learn for everyone else. Even when clearly understood, terms like “Archive” and “Inbox” started to feel out of place in a podcast player, since podcasts are supposed to be fun, not getting to Inbox Zero™

Castro now uses more familiar language to help navigate the app:

These changes don’t impact functionality — Castro users can still triage episodes of their favourite shows as before — but we hope these tweaks will make the app’s workflow a little easier to pick up and master.

From the start, we’ve designed Castro to be a powerful upgrade over the playback and management experiences offered by other podcast apps. Today’s updates are designed to help make the power of Castro accessible to more people: The new Discover tab makes it easy to learn about new shows, better search finds the shows listeners already know, and by cutting down on jargon it’s easier than ever to move to Castro.

Castro is now part of Tiny

We have some news to share. Tiny has purchased a majority stake in Castro. We are still shareholders and will continue working on the app full time.

Who is Tiny?

Tiny owns a range of companies you’ve probably heard of, like Dribbble and Flow. It was founded by Andrew Wilkinson and Chris Sparling. Andrew previously founded MetaLab, a design agency who worked on many high profile projects: they designed Slack from the ground up. Chris served as MetaLab’s CFO until 2015 when he left to start Tiny with Andrew.

You can read more about their investment approach and philosophy on their website and in this Medium post.

Tiny felt like a good partner for a few reasons:

Why sell Castro?

Castro has reached a size where the demands of running the business have been pulling us in too many different directions. We haven’t been able to focus as much on the core work of designing and building a product. Selling to Tiny gets Castro access to more resources, contacts and expertise. By growing the team we can specialize our roles to be more focused individually and get more done collectively. We can get back to what we’re good at and what we love doing.

The podcasting industry has been consolidating lately. WNYC bought Pocket Casts this year, Anchor is backed by VC investment, Google launched a podcast app for Android, and Apple is paying much more attention to podcasts than before. We want Castro to stay relevant and we want to keep having an influence on the direction podcasting takes.

What’s Next?

We’ve started work on Castro 4. The plan is to improve the design to bring more listeners into the Castro flow. We’re excited, because for the first time in five years of work on Castro, we’ll have the resources to focus exclusively on it as product designers and developers, without contract work to distract us, and with a team around us to handle the administrative tasks.

FAQ

What happens to Supertop?

Castro is owned by Tiny but Supertop is still the name of Oisín and Pádraig’s collaboration. We’re shareholders and full time employees of Tiny now, so Supertop will be a bit quieter.

Will you keep podcasting?

Yep. Our next episode will be about the acquisition.

I have another question

We realize that this is a big change and that many Castro listeners may have concerns — here are our direct emails if you’d like to talk with either of us: [email protected], [email protected].

We’re extremely grateful to everyone who has brought us this far. We think this is the right direction and that together with Tiny we will take Castro to a place we couldn’t have gotten alone.

Now Playing in Castro 3.2: Audiobooks, Extracted Audio, and more

Sideloading is a Castro-exclusive feature that makes it possible to easily add any audio file to your listening queue — even when they’re not part of a podcast feed.

Now, with Castro 3.2 we’ve made it even easier: The new action extension in the iOS share sheet lets you add any audio file you find online straight to Castro with just a couple of taps. Castro will even extract the audio from video files you sideload.

Easily add any audio file from the Web to your podcast queue

Sideloads open up Castro’s advanced player features and queuing system to play any audio — not just files that happen to be available in podcast RSS feeds.

It’s common to discover, or be recommended, single episodes of shows. Sideloading makes it really easy to add those podcast episodes to your listening queue without having to subscribe to another full feed and seek out episodes individually.

Podcasting aside, there’s a lot more audio on the internet than just the subset available in podcast form. Sideloading gives podcast fans easier access to a large part of the audio ecosystem that was previously unavailable, and opens up a whole new world of spoken word audio. It’s perfect for listening to:

When we first added Sideloads to Castro, users needed to manually save audio files to iCloud Drive. Castro 3.2’s new Action Extension makes it easy to grab audio straight from Safari on iOS using the system Share Sheet.

How to Sideload any audio file

Sideloading is available as part of a Castro Plus subscription. If you’re not already a subscriber, you can start a 7-day free trial today tapping the settings cog in the app, then the big green Castro Plus banner

To get set up, you just need to add the Sideload action to your iPhone’s Share Sheet (If you haven’t configured it before, check out iMore’s excellent guide).

Once it’s set up, sideloading an episode is as easy as tapping the share button and choosing the “Sideload to Castro” action.

Tips for Sideloaders

We’re building Castro for you

We released Castro 3 earlier this year with trim silence, chapter support and a redesigned player screen (among many other features). We added Sideloading and Chapter Pre-Selection in August and now Castro 3.2 to double down on Sideloading. Castro can now be used to play almost any audio on the internet.

We’re proud to be delivering something something truly unique and valuable to our subscribers. If you’re a Castro Plus subscriber, thank you for your continued support — if you’re not yet, we offer a 7-day trial.

Podcast: More Users or More Subscribers?

We discuss how we can better introduce the features of Castro and improve the Castro Plus subscription pitch. To do that we need to better understand how people are using the app have better ways to measure whether changes we make are working.

Release Week: Castro 3 and Castro Plus

Download Castro 3 for free on the App Store

We released Castro 3 a week ago, tweeting:

Castro 3 is out now:

  • Beautifully redesigned player screen
  • New player engine built from scratch
  • Apple Watch app

With this update Castro became free to download from the App Store. The triage features, and almost everything else, that users loved in Castro 2 are now free to use for everyone.

We also announced Castro Plus, an optional subscription for advanced features:

  • Trim Silence
  • Enhance Voices
  • Mix to Mono
  • Chapters
  • Per-Podcast settings
  • Skip Intros
  • Episode Limits
  • Night Mode

Night Mode and Enhance voices were already available in Castro 2, so customers who bought that still have access to those features whether they subscribe to Castro Plus or not.

We discussed this move to Free + Subscription in recent episodes of our podcast. There are a few popular exceptions but we strongly believe that paid up front apps with perpetual free updates are not sustainable for building an indie business on the App Store. Paid updates and free trials (if Apple introduce them) have worked for indie developers on the Mac for years, but the prices for indie Mac software are much higher so I’d be wary of suggesting that those features alone would be enough to make indie software more viable long term on iOS.

Aside from business model changes (and some new features like Mix to Mono) our main focus when developing Castro 3 was to catch up on as many features from other podcast apps as possible. Ryan Christoffel picked up on this in his MacStories review:

If an absent feature ever kept you from sticking with Castro 2, that almost certainly won’t be a problem anymore. Castro 3 addresses nearly all of those “one missing feature” requests in a single release. […] Castro 3 is everything Castro already was, but better. It’s the app that Castro fans have always wanted.

When we released Castro 1, almost 5 years ago, we were driven largely by a frustration with the visual design of other podcast apps, and so the visuals were what set that first version apart. In the intervening years however, we’re happy to have been able to bring much more to the table, and now have an app that serves podcast enthusiasts’ needs in a powerful way. Ryan continues:

Castro has always had its core attractions, and those remain what they were; Castro is still Castro, but better. Its main appeal was once to a select group of users with specific design preferences, but now Castro has truly come into its own: it’s become an app that serves nearly any podcast fan’s needs.

Glenn Fleishman made Castro 3 a Macworld Editors’ Choice, which is an honour:

I’ve found Castro’s triage approach suits my style of podcasting subscribing and listening better than playlist-driven ones, and if that sounds appealing to you, the rest of Castro 3’s improvements make it an easier recommendation as well.

On iMore, Christine Chan compared Castro 3 to Overcast, asking which podcast app is better?

I’ve always enjoyed the aesthetic of Castro over Overcast but continued to use Overcast because of the feature set. Now that Castro 3 brings about a slew of powerful new features, it’s a much harder choice to choose between the two. Each one has their own strengths and weaknesses, but the playing field is much more level now.

We worked hard during development to try ensure Trim Silence would be a worthy competitor to Marco Arment’s Smart Speed® in Overcast; we didn’t want to just check it off a feature list, so we were happy that Christine echoed a sentiment we’ve heard from other reviewers and customers:

After testing out Castro’s Trim Silence, I believe that it’s on par with Overcast, and a great addition to Castro. Voices still sound natural, and I definitely don’t notice as many awkward silences in shows, as it’s meant to be.

Last week was a whirlwind of responding to customers emails and tweets, catching up on reviews, trying to interpret stats from iTunes Connect, selling and buying houses, and even writing a little bit of code.

On Thursday we tweeted:

Castro 3 has been downloaded more times in 3 days than Castro 2 was in 2 years. 😘

That quickly became our most liked tweet of the week. It’s lovely to see how many people are enthusiastic and hopeful about the future of Castro.

It’s important to note that increased download numbers really are only the first step in a successful transition to this new model, we need a certain percentage of those downloads to convert to subscriptions. I’m happy to report that opposition to the subscription model, which we expected and were prepared for, has been from a vocal minority and the vast majority of feedback we’ve received has been from customers saying they’re happy to pay for an app they use so frequently.

Since both subscription tiers ($3 for 3 months, or $9 for a year) start with a 7 day free trial, today is the first day that actual paid subscriptions begin and tomorrow we’ll know what our initial subscriber count is. Over the coming weeks we’ll get an idea of how many new subscribers are signing up each day. It will take a few months before we know how many subscribers on the quarterly plan renew for a second term. All these factors will contribute to us determining whether we can meet our target subscriber count in a reasonable time or if we’ll need to rethink our marketing efforts and/or product roadmap.

We’re hopeful, quietly optimistic even, about this transition; but in many ways the work towards having a successful and sustainable indie software business based on recurring subscriptions is only just beginning.
