A flashcard app that decides when you should see a card again - so you review each one right as you're about to forget it, and never a moment sooner.

Build a collection
Add cards by hand, import a CSV to bring in a whole deck at once, or search for existing collections created by other users.
Study when it's due
needspace queues each card right as you're about to forget it - never a moment sooner.
Track your progress
Streaks, review history and mastery stats show your memory getting stronger.
