I was looking for a place to share my two favorite Mastodon and Lemmy clients, they are called Voyager Connect for Lemmy and Moshidon
(the official Mastodon app works fine though, you just can’t follow new hashtags from it)
They are very good, try them out sometime 👍 (I’ll update this post whenever my opinion changes)
Liftoff is available on iOS too! It’s probably the exact same app, but I find the interface a bit too cluttered for my tastes. But it is packed with features!
