Went to see what is Smarterer about. Is it me or the UI of their testing product looks very much like Duolingo? Are they related?

  No relation (I'm a co-founder). I'm guessing it's a case of convergent evolution. Our testing UI has been pretty similar since the beginning, 4 years ago (not sure if they existed then or not). Edit: I realized after typing that it was confusing... I meant self-similar not similar to duolingo.
