This repository was created with the intention of providing a definitive list of all iOS apps with support for the federated social software Mastodon. This should include Mastodon Clients, naturally, but it should also include utilities like Linky as well as any other apps with Mastodon support (for the moment).
I wrote about this in my blog post "The State of Mastodon iOS Apps."
Please do contribute/communicate if you see errors/missing apps in this list.
