You choose: 5, 10, 15 or 20 new words a day.
You pick the number when you start, and you can change it any time in Settings. The app suggests five to begin with, and offers ten once your words are sticking. On a day with many words to review it gives you fewer new ones, so the lesson does not grow too long.
A lesson has two parts. First the new words: each one's card, then the turns from memory. Then three short rounds over today's words: from the meaning to the word, from the word to the meaning, and mixed.
You can stop any time; the app keeps your place for the day.
