"GitHub".

Does "for your OS" really add anything?

I was thinking that the GitHub "app", for those unfamiliar with using git, would be some friendly front-end, but the linked page suggests it's just the "git" command-line tool? I don't think I've seen those called "app"s before, but perhaps it'd make sense to normal people. I can use CLI git even if I am already familiar with using git, so the construction here just seems odd to me.
