How the revision schedule works
Each card sits in one of five boxes. Press Got it and it moves up a box; press Again and it drops back to box 1. Cards in a higher box come back less often:
Box 1next day
Box 2after 3 days
Box 3after 7 days
Box 4after 14 days
Box 5after 30 days
A session is up to 20 cards (at most 10 new ones), so ten minutes a day is enough. Studying a card counts towards your daily streak.
