It works for me.

It's different. I used it many years ago the refresh my Italian, but stopped before I could get to anywhere.
Back then it was a fairly large program with language packs. I used Duolingo a little as well (to refresh my German, but I stopped before I could get to anywhere..., hmm I see a pattern forming here... anyway) and it is really different. Rosetta should be more professional.
