How it works

Spaced repetition for LeetCode. You solve a problem once, then LeetRecall brings it back before you forget it.

Step 1

Complete a quick self-assessment

Choose how comfortable you are with each pattern: New to me, Somewhat familiar, or Comfortable. This helps prioritize early reviews.

Step 2

Your account begins with a preloaded queue from a curated set of problems, so you can begin reviewing immediately instead of planning from scratch.

Step 3

For each card, mark pass or missed. Missed cards return sooner, while stable cards are spaced further apart over time.

Step 4

When you pass a card, 1–3 related problems that use the same technique are queued automatically. You practice the same concept before moving on.

Step 5

Track your progress by pattern and use settings to tune your daily card target and pacing preferences.
