How review works

The app tracks how well you know each word you practice and brings it back shortly before you would forget it.

Timing

Every word you practice has its own schedule. A right answer stretches the gap, from days to weeks to months. A miss brings the word back the next day.

学习, answered right each time

What counts

Any card you answer: your decks, quick practice, and Review itself. There is nothing to set up.

One round

Picked when you start it, at your round size. Half is your schedule: words whose time has come and your recent misses. The other half comes from the waiting pile, mostly words you half-know, plus the occasional long-forgotten one. Do as many rounds as you feel like.

5 on schedule 3 half-known 2 forgotten

The waiting pile

Words a round does not reach wait their turn. When you answer a word you still remember after a long gap, it moves far ahead, so the pile shrinks faster than its size suggests.

A word from the pile, answered right once

waits a month not back for two months

Missing days

Nothing resets and nothing is lost. The words wait until you come back, and words you missed recently keep their place at the front for a week.
