Where most vocabulary apps simply tell you if you get a word right or wrong, this one will tell you which parts of the definitions you got correct, helping you learn the words. It does this by letting you type in the definition, and then highlighting the words you go right in blue, as well as telling you what percent of the words you got correct.
The app also allows you to store multiple "lists" of different words for different subjects, or quizzes. You can set words as "inactive", temporarily disabling them within the quiz. You can also check your average percentage for that word.
