This app SUCKS! I used to like it but now the heart system update it makes me want to stop learning Ukrainian! the language is sorta accurate but the heart system is discouraging, you can only make 5 mistakes before you have to quit your lesson. if you are in the middle of a lesson you either have to get all of the next questions right or quit the lesson and lose your progress. The hearts force you to be almost perfect when they say practice not perfection. This WAS a good app, FIX IT PLZ
