It has the most useful bits of functionality of Scala, with a simpler UI, and as a web rather than desktop application.
I'm pretty sure this predated the programming language. I can't find a source on when Scala (the microtuning one) first appeared but it existed when I first got into this stuff around 2004, and I didn't have the impression it was new at the time.
Scala the programming language had its first public release on 2004-01-20[1].

From my perspective as a Linux user and developer, one problem with it was the non-commercial-only licence which, while obviously reasonable, prevented it from being packaged in many Linux distributions. If it wasn't for that, your "apt-get install scala" might well be installing this application rather than the programming language.
Or my favourite restaurant in Ibiza. [2][3]
Though I did grow up with Scala the company on my tv as the local cable tv company was powered by it. Now I work most of the time using Scala the programming language.

Edit - looks like this is as old as Scala the programming language.
