I have found that it works better for me not have unlimited hearts. I make my mistakes, and in I am not ready on a level then I have to repeat it. And either way I then do practice rounds to fill my hearts back up to full (I try to always leave the app with full hearts). In the times I have had SuperDuolingo for free Have been annoyed that I can just keep plowing through mistakes (really: lack of knowledge), and don't have to really learn things before moving on with them... I just have to guess right once for each question. But I do agree that DuoLingo is all about learning by making mistakes. I wish they had a bit more focused teaching for grammar, at least it would help me with the Hungarian. For a few items I have had to go outside the app for lessons on what I am just not getting by repetition.
