I'm a paying user of Overcast since the very beginning. Happy to support indie devs like Marco Arment. And it's just a better podcast app than Apple's :)
Really enjoying Artifact. My only complaint is that all the links go to unoptimized webviews of the source, so you get all the pop-ups, in-line ads, cookie opt-ins, etc.
After using Instapaper and then Pocket for years, I've started using Matter a few months ago. Really great product, thoughtfully designed and built, with none of the shortcomings of the other two. Definitely recommend trying it out.
