So @MonaApp is out today and immediately takes the crown for most customizable Mastodon client to date. Multiple columns on Mac and iPad, split-screen on iPhone (!), and TONS of settings you can tweak. Insta-purchase for me, with no subscription.
Mona: A Unique Mix of Customization Options and Features You Won’t Find in Any Other Mastodon App
Mona is a brand new, highly customizable Mastodon client from Junyu Kuang, the developer of Spring, which is one of the few remaining third-party Twitter clients that still works and pioneered many of the features found in Mona. Mona, which is available on the iPhone, iPad, and Mac, is a power-user app through and through.
