It’s a Lemmy front end, very clean. On your local device it runs some algorithm that tries curate a better feed for you based on your interactions with Lemmy. Not unlike many larger social media sites.
You can also sort by the normal filters like ‘active’, ‘new’, etc.
I read about it burried in some comments.
It’s great to see so many front ends and experimentation within the Fediverse.
Another interesting frontend is tesseract.dubvee.org which has some clever features, and good mod tools.
I tried to switch, because it is really nice. But coming from sync, how having to swipe back to the main feed from a post made me look elsewhere. You have to start your swipe at the far left of the screen, vs just swiping anywhere.
I’ve gone from sync to voyager too and yeah, that does bother me. Sync really does have the best UX, UI and performance but it’s a shame it’s basically been abandoned.
