LeetCode Timer is an essential Chrome extension for coders focused on efficient time management during LeetCode problem solving. It automatically tracks the time you spend coding on each problem, starting when you begin and stopping upon submission.

You can set custom time limits tailored to problem difficulty—easy, medium, or hard—helping you stay on track and sharpen your coding speed. Additional features include the ability to hide difficulty levels, acceptance rates, and locked questions, plus a draggable timer that supports all LeetCode UI modes including old, split view, and dynamic layouts. Regular updates ensure compatibility with LeetCode's interface changes, along with multiple bug fixes and interface improvements.

User reviews

Users appreciate the LeetCode Timer for effectively managing and tracking time spent on coding problems with a simple, unobtrusive interface. However, multiple users report issues with permissions overreach, inaccurate timing when switching tabs or external editors, occasional timer display failures, and compatibility problems with different LeetCode UI versions. Suggestions include improved permission requests limited to LeetCode, automatic timer control on accepted submissions, and features to track coding time outside the browser editor to enhance accuracy and usability.

Pros

Helps manage time effectively while solving LeetCode problems.
Simple and unobtrusive design with minimal screen space usage.
Useful and helpful for tracking time spent on coding problems.
Starts timer automatically and supports manual control.
Provides motivation and positive reinforcement for practicing coding problems.

Cons

Requires permission to read and change data on all sites instead of limiting to leetcode.com by default.
Timer sometimes stops or pauses inaccurately when switching tabs or applications, leading to incorrect time tracking.
Compatibility issues with different LeetCode UI versions; does not fully support old UI or updated UI versions.
Timer sometimes fails to display on LeetCode, necessitating disabling and re-enabling the extension.
Ignores time spent coding in external editors since the timer pauses when switching away from the LeetCode tab.

From where does it store the time that I take on any question, as it did not require any signup? Yesterday when I reattempted a question that I solved a month ago, the timer started from where I left it after solving it that time.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

LeetCode Timer requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.
