The header of the home screen displays the user's progress: a card for the number of words he has learned, a card for the number of new words he needs to learn, and series he is presently learning. There is a progress indicator for the study on the series' image. The header of the screen shrinks and only shows the cards as you scroll.
The feed below displays the available series, broken down by genre.
The navigation bar has a "Catalog" button. We'll talk more about the catalog later.
The bottom menu consists of 5 parts: main screen, favorite series, dictionary, trainings and profile.
