 AntennaPod mainly uses three directories for its search feature:
 * [Podcast Index](https://podcastindex.org/) (ask your hoster how to add your podcast, or add your own podcast via the [API](https://podcastindex-org.github.io/docs-api/#get-/add/byfeedurl))
-* [iTunes](https://podcasts.apple.com) (add via [Podcast Connect](https://podcastsconnect.apple.com/))
+* [Apple Podcasts](https://podcasts.apple.com) (add via [Podcast Connect](https://podcastsconnect.apple.com/))
