...or Thunder, which is very similar to Liftoff. I use them pretty much interchangeably. Both are built with Flutter, have similar UX and performance and they work on both Android and iOS.
I've tried thunder, and the UI looks really good, but for some reason when I try to scroll up on a feed the whole list starts shaking, almost as if the posts on the top of the list are changing size.
And I don't understand how people say the other apps are better, especially Voyager. I've used them all and they're all a fraction of the quality of Sync.
