As of the time of writing this, Matatown's not an app in the real world, and the module doesn't represent the way that the app is described in the story, either.
This kind of nebulous half-reality permeates the project's overall exposition.
But what if it was real? What if you could play the game, and go inside the world of Matatown, and make your own version of the program all at once?
It sounds like a dream, but it's not. It can all be yours, coming soon in Strangers: VHZ.
