I am currently enjoying wefwef, jerboa, and thunder the best. Liftoff is good, but not connecting with all instances (lemm.ee, etc). I have tried connect, not my style. Personally am waiting for Sync, was my favorite on reddit.
Right now all the apps are being developed at lightning speed
I'm on iOS so the easiest to get running for me has been wefwef since it's a webapp (the other apps aren't on the app store yet). It copies the apollo layout.
If you're on android then look around, there are probably better alternatives.
boost for lemmy is coming soon on google play store (at least to G play store) Very similar to boost for reddit we had before. Will personally probably install it.
