Loops, like everyone rightly said, but while this initially peaked my interest, at this point I'm a little skeptical about this project. Dev seems very keen to overhype and tease new features, but usually fails to deliver, like the webUI that was supposed to be days away last year but still doesn't exist. For a fedi platform, not being able to access it via a browser on a desktop is the most bizarre thing to me. I'd hate for fediverse tech to follow this mobile-only trend.
