Spaced revision
Notes come back at 1 minute, 3 minutes, 9 minutes, then 1 to 30 days — right as memory starts to fade.
After you show an answer, you choose how soon the note should return. Short gaps catch slips while you still remember the session. Longer day gaps lock the same idea into long-term memory. A time strip at the top of revision shows how many notes sit in each bucket.
