Castro has long been one of the premier podcast clients on iOS, and its excellent version 2 – with an innovative triage system and delight-inducing design touches – helped solidify it as such. Those strengths in 2.0, however, were mitigated in part by the absence of a few key features that competing podcast apps tout. That changes with Castro 3.
If you're unfamiliar with the app, Castro's centerpiece feature is a triage system involving an inbox and queue. The premise is that, with the rising popularity of podcasting, there are more great podcasts available than ever before. If you subscribe to lots of shows, the standard episode management tools found in competing apps likely aren't sufficient. With Castro, by default new episodes of shows land in your inbox, and can then be sorted to the top or bottom of your queue and downloaded, or archived if they're not of interest to you. It's an elegant solution to the problem of podcast overload, and, thanks to customization options that allow you to make certain shows populate the top or bottom of the queue automatically, it's a system that works for you, tailored to your listening preferences.
Castro's triage system clicked with me the first time I tried it, and I used the app daily for nearly a year. Eventually though, I became more selective about the portions of podcasts I listened to, and Castro's lack of chapter support sent me elsewhere. I've seen comments from other prospective Castro users who were similarly turned off from the app due to one missing feature – and often, this feature was different for different people.
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. Trim Silence is Castro's take on Overcast's Smart Speed; full chapter support is now present, as is a new Apple Watch app; the player screen has been fully redesigned; Mix to Mono improves stereo mixes that are hard to hear; and finally, there are excellent new per-podcast controls in a variety of areas. Perhaps the only thing still missing is an iPad app.
Castro 3 is everything Castro already was, but better. It's the app that Castro fans have always wanted.
