Can you recall 하루 without looking? Try three cards from “Days, Hours & Durations” and see how LENGO decides when to show a word again.

How does LENGO decide what I practice?

Every word has a strength. New words come first, then the words that are due: a weak word comes back after 10 minutes, a strong one after three days to a week. A right answer makes the wait longer, a wrong one brings the word back sooner.

How many new words do I learn a day?

Seven to start with. You can set anything from 3 to 20 new words a day.
