The author created a podcast player for iOS called Podcatcher, using a combination of Racket and Swift. The app includes audio enhancements like an equalizer and silence trimming, and is free from ads and tracking. It lacks cross-device sync via iCloud and has a simple UI. Future updates may include a sleep timer, support for favorites/bookmarks, and a watch companion app. The development process led to improvements in Racket and OSS components. The app comprises 6,392 lines of Swift and 4,965 lines of dense Racket code. The author is considering making the app’s source code available based on interest.
