I’m new here. A refugee from Reddit. In my opinion this is awesome but unless a decent app is available I don’t think it will every attract a broad audience. I am no expert though and maybe an app does exist that no one is aware of.
I don't think there will ever be an official app, due to the open nature of the service. I am using Jerboa, but its still very rough. I will try Lemmur now, it has a nice UI from Google Play screenshots but no reviews.
I don’t need it to be official really. I just want some QoL features. I was an Apollo user so I am hopeful that Christian will build an app for the fediverse.
