I was looking for a place to share my two favorite Mastodon and Lemmy clients, they are called Voyager Connect Boost for Lemmy and Moshidon for Mastodon (if you are really serious about privacy I recommend Connect still)
(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)
Moshidon is better if you want to check if pictures have alttext. Moshidon can show the public timeline of other instances in your feed too. You can get more input this way. Try it out, play around with both and decide which one fits most for you 🌞
