Spaced repetition is a learning technique that involves reviewing information at increasing intervals over time. It's based on the psychological spacing effect, which demonstrates that we learn more effectively when we space out our learning over time rather than cramming. Our tool applies this technique to LeetCode problems, scheduling reviews based on your self-rated understanding to maximize long-term retention.
