Automated spaced repetition queue for LeetCode, Codeforces, GFG, HackerRank, and CodeChef. Never forget what you solved.
Recall schedules your DSA revision automatically. Solve once. Remember forever. 2–3 problems, automatically selected by your schedule. Mark each one and you're done. Add any problem from LeetCode, Codeforces, GFG, HackerRank, or CodeChef. Title, difficulty, and topic fill in automatically. Recall assigns your first revision in 3 days. After that: 7, 14, 30. The interval adapts to your recall confidence. Open Daily Revision. Mark each problem Clean, Shaky, or Struggled. The algorithm adjusts. Your streak builds. Automated 3 → 7 → 14 → 30 day revision queue that adapts dynamically based on your confidence rating. Clean advances the interval, Struggled resets it, and Shaky repeats. Instant…from recallx.tech
