Nice audio-processing features; sync lacking, issues with buffering/UI responsiveness – Castamatic Podcast Player Review

I really like the audio features (leveling, gap reduction, speed-up), but this app has a few major issues with syncing, playback, and responsiveness. First, I've set up a bunch of playlists on my phone but those dont sync over to my other iOS devices. Also, the UI often freezes up for several seconds when loading lists. Also, the audio often stalls out while the app is apparently rebuffering, and sometimes audio gets caught in a loop (I assume this is also related to a buffering issue). If the developer can address the above issues (and add an option for 1.75x playback, which would be my preferred playback speed), I would consider this a 5-star app.
