On the other hand, for best iOS/Mac podcast app, I haven't been completely happy with any for years. New ones with smart speed - great feature, but I like one feature above all else.
My favorite app was Instacast for iOS because it let me add time stamped bookmarks/notes. Audible has something similar. None of the apps mentioned in Product Hunt or his blog post seem to support this. Such a bummer. I paid for Instacast 5 before it was removed. It started crashing at launch on iOS 10 however.
Edit: I recognize not many people, likely a single digit percentage of podcast app users would care for bookmarking/notes (thanks Void_)
