I do not like the new Duolingo changes. It seems like it encourages one to give up if they fail multiple times during a lesson.
Health is only available on iOS, so you can simply use the website to avoid the system.
I still keep hoping DuoLingo will un- "fix" the interface. It used to be great. Now, it's far too slow (both for the user and lag). I'm guessing it's better for touch screen users, but MUCH worse for keyboard touch-typers.
I used to spend a few hours every day here, but haven't spent more than a few minutes every couple of months for the last year or so....just hoping the GUI will be fixed.
No such luck, yet.
