Mastodon isn’t an app or a site. It’s a social networking/microblogging service. So, you could use an app to access a Mastodon server, but that server wouldn’t be “the” Mastodon site, just “a” Mastodon server/instance.
Maybe things were much more centralized in 2016, when you first tried it? I only joined last year.
Sorry, my brain doesn’t know how to parse that.
