It's among top 2 FOSS lemmy android apps in my opinion. Thunder is if not smoother as smooth as Sync but it lacks some polish, LiftOff is definitely designed with fediverse in mind thus has very interesting functions, Jerboa is basically Boost UI wise, missing a lot on the functionality front, Infinity, however it was the last time you checked it out on alien site except bugs related to API differences. And yes I keep shuffling between all of them and then some.
