Castro
Castro is a design-focused iOS podcast app with a smaller but dedicated user base who care about a clean inbox-style listening workflow.
PodStack editorial · Product research. How we review tools
Castro built its identity around an inbox-style approach to podcast listening, where new episodes land in a queue you actively triage rather than an endless auto-playing feed. It appeals to listeners who like intentional listening habits.
This fits shows with an audience that already appreciates thoughtfully designed apps, often overlapping with people who also use things like Pocket Casts or Overcast rather than the default Apple app.
The gotcha is scale, Castro's user base is meaningfully smaller than the major players, so while it's worth being listed, don't expect a noticeable bump in overall numbers from it alone.
Treat it as one more distribution point your standard RSS feed reaches automatically, not something requiring active management on your end.
