How to use
Due today is your queue: overdue reviews first, then new cards. Other filters let you review any card.
Recall the answer, then show it. Grade honestly: Again brings the card back today, Hard grows the gap a little, Good grows it by the card's ease, Easy grows it most.
Each grade button shows when you will see the card next. A card counts as known once its gap reaches three weeks.
Keys: Space or Enter shows the answer, 1 to 4 grade it.
