This application helps you learning vocabulary by using the flash card (Leitner) technique. After downloading an appropriate database from our server, or entering cards by yourself, you can start a quiz session where the application will present you cards and let you choose whether you want to see the card again (if you didn't know the corresponding translation), or not (if you already knew the translation). Since the application keeps track of your knowledge concerning each card, it can cleverly choose which card it shows you, to shorten the time needed for you to master the content of each card. 更新内容： 为您优化了体验细节。
