Poor updates

Used to love this app. The health system is a big issue and can cause you to stop being able to learn. You can go back and "practice" precious lessons and it makes you think you can gain health back, based on the picture of the heart on the button, but it doesnt actually give you any more health. Also, when beginning a new section it expects you to know the new words without being taught so when you mess up, because you havent learned the word, you lose a health bar. Poor development of this app.
