Sideload to Castro
I have been a regular podcast listener since at least April 17, 2005. Over the last 14 years I have tried a lot of podcast apps. Switching podcatchers has always been easy thanks to the freedom of the open web (RSS) and the transparency of XML (OPML).
For the last couple of years I have been using Apple's Podcasts app exclusively, but that all changed when I learned about the latest sideloading features coming to Castro.
Castro now lets you send audio from your favorite YouTube videos into your podcast queue! Just browse to the video you want to hear and “Sideload to Castro” using the iOS sharesheet. Once the YouTube audio have been downloaded into the app, you can use all of your favorite Castro features like Trim Silence, Voice Boost and variable playback speed to enhance your listening experience.
I listen to a lot of content on YouTube, but I don't always need to watch the video. Sideload to Castro works great with talking head videos, documentaries, or any content I want to listen to later; even without an Internet connection!
The only thing that could make Sideload to Castro better is if Castro could automatically sideload audio from my favorite YouTube channels in the background using RSS.
