Developed by Piotr Woźniak in 1987, the SuperMemo 2 algorithm calculates optimal review intervals based on how easily you recall each word. The better you know a word, the longer the interval before your next review.
New words start with short intervals: 1 day, then 6 days
After each review, rate how easily you recalled the word (0-5)
Algorithm adjusts next interval based on your rating and history
Review just before you're likely to forget, maximizing efficiency
