Haven’t heard of Mastodeck. Gonna have to check it out. But to add some android apps to your list Megalodon treated me well when I was using it and Moshidon looked good too. For those that don’t need something as crazy as Mastodeck on desktop though, there’s Mastodon’s built-in advanced view as well. I was never a Twitter user, but Mastodon and Firefish have been very fun to check out.
