I use Connect for Lemmy. It's as free, but closed source. The developer is available and fairly responsive in !lemmyconnect@lemmy.ca

I recommend opting into the beta version on the Playstore to get some features a little earlier. For example, Lemmy 0.19 introduces the new Scaled and Controversial sort options, which are amazing -- particularly Scaled if you're subscribed to smaller communities. However, Connect for Lemmy only has that sort option in the beta at the moment.

The only thing I don't like is that you cannot paste images from the clipboard into comments.
