About LeetClock
Track your LeetCode solve times automatically — with zero manual toggles, stopwatch clicking, or context switching.
LeetClock runs seamlessly in the background while you code. It measures your active problem-solving duration, logs your history, syncs metadata into your LeetCode Notes, and delivers instant submission feedback when you get that Accepted verdict.
