The apps are listed on the official website. The official app is in public beta, but I hope it gets a public release soon. You can follow @pixelfed@mastodon.social on mastodon for updates. There are also 3rd party apps, but I haven’t tried any.

There are many, but right now it’s definitely “Infinity for Lemmy” ❤ (Available from IzzyOnDroid F-Droid repo).

There is also joshuto, another ranger clone, written in rust.

I use ranger with zoxide plugin, very handy. I even use it inside neovim as well, using rnvimr plugin.
