I studied German for 3 years in university, dabbled in German duo-lingo, and completed all German courses on Memrise.
I don't see how one can learn German fluently using Duolingo (or even Memrise, which I think is much better). It's great for vocabulary, but I think understanding the grammar requires understanding the theory which I didn't see when I used these applications.
