> The biggest problem to me with Duolingo that it doesn't explain certain language rules (I am learning German) and you have to brute-force until you "get a feeling" and memorize patterns. I'm not trying to be contrarian but, in my opinion that's a strong point, not a weakness. I work with language learners a lot and many of them spend a long time looking at explanations of foreign languages in their own language. This basically never works. The people who really progress dive in and let their brain soak up the new rules and patterns. In a metaphor: reading grammar explanations is like try to learn to play the piano by reading about on how a piano works. You might learn a lot, and even work out how to play simple tunes but your fundamentally practicing the wrong thing.
