This is perfectly serviceable as a tool for learning some common nouns, but it doesn't really extend beyond that. And perhaps I shouldn't judge it for something that it not only doesn't do, but couldn't possibly do (how would it frame grammar mechanically, for example?), but that doesn't make it suddenly 'fun.' After all, it's just glorified flash cards. And I definitely like it more than boring old flash cards, but it's still just that.
I have it in Korean and French.

Basic 'round-the-house interactive vocabulary learning, more suited toward the beginner level. French, Italian and Korean are available in the free edition, though there's quite a selection of other languages that you can purchase.
