No, I am using Learnables, plus various apps (like Poptok), and some duolingo thrown in (we do that together, but not as often as Learnables). I have my German books from high school which I pull out sometimes.
I thought about doing native materials. When I looked at them for the level he is (beginner!), however, I thought he wouldn't like the "little kid" graphics as he calls them. But maybe I'll look again. Hmmm.
