Spaced Repetition by Wärn app analytics for December 17

Remember anything. Forever. Start by creating your own cards for what you want to remember. Ukulele chords, mathematics, or your friends’ birthdays. Question on the front and answer on the back. Then once a day the app prepares a test for you. You decide which cards you got right, and which you need to practice more. Cards start at level one. Cards you get right are moved up one level. Cards in higher levels are reviewed less frequently. This makes it possible to remember anything. Forever.
