Honestly I just like the UI, it looks great and it’s fast. It’s also customizable enough for my needs, and is native to iOS so it follows its design/UI rules. In terms of space it is indeed a bit bigger, but honestly it doesn’t bother me that much it’s only 40MB more. Last but not least, the dev team is very helpful and answers quickly on their Matrix chat.
I’m curious though, what features do you think it lacks?
Create/join communities in your field, on Mastodon follow the hashtags and most importantly feed them with posts even if no one answers or interacts, someday you’ll reach the audience you’re looking for
