Based on the ‘a word a day’ concept, this app provides up to 12 words a day of your choosing. All words ‘learnt’ are tested repeatedly thereafter, on a basis of decreasing regularity, if answered correctly, as you gain familiarity with the said word. Vice versa, if incorrectly answered, the app will adjust to test you more on the word, or ‘deactivate’ it, while you learn other words meanwhile. Pace yourself as you go through the almost a thousand common and popular Czech words available in the app. In just a matter of weeks, you will have an essential knowledge of the Czech vocabulary !
