About this extension
Master the Technical Interview with Discipline and Data.
Green Timer is the ultimate productivity hub designed specifically for LeetCode. Move
beyond simple time-tracking and transform your practice into a data-driven journey.
Designed with a sleek "Glass-Terminal" aesthetic, Green Timer provides the professional
environment you need to build consistency and solve with speed.
⏱️ INTELLIGENT TRACKING
* LeetCode Auto-Detection: Automatically captures the problem name and number as you
browse LeetCode.
* Smart Automation: Opt-in to auto-add problems and auto-start timers the moment you
land on a question.
* Custom Status Manager: Define your own journey with color-coded statuses like "Hint
Assisted," "Struggled," or "Mastered."
* Multi-Timer Management: Solving multiple problems? Manage several independent
stopwatches simultaneously.
📈 DEEP PERFORMANCE ANALYTICS
* Problem-Specific Deep-Dives: Click the analytics icon on any question to see your
solving speed trends over multiple attempts.
* Visual Insights: Beautiful line charts visualize your progress, alongside automated
metrics for Average Speed and Personal Best.
* Yearly Activity Heatmap: Track your consistency with a GitHub-style contribution
heatmap.
* Daily Goals & Streaks: Set targets and visualize your progress with live-updating goal
indicators.
🏷️ SMART TAGGING SYSTEM
* Centralized Metadata: Tags are linked to the problem, not just the attempt. Categorize
a problem once, and it stays synchronized across your entire history.
* Multi-Select Filtering: Powerful "AND" logic filtering allows you to find specific
practice sets (e.g., "Hard" + "Dynamic Programming") instantly.
* Tag Distribution: Visualize your most practiced categories and drill down into them
with a single click.
🎨 PREMIUM UI/UX
* Glass-Terminal Design: A high-contrast, distraction-free interface optimized for long
coding sessions.
* Instant Theme Switching: Toggle between Glass-Dark (#00ff00) and Terminal-Light
(#008000) modes instantly.
* Responsive Dashboard: Access your full data suite via the extension popup or the
immersive full-page dashboard.
🛡️ PRIVACY BY DESIGN
We believe your study data is yours alone. Green Timer is a zero-leak extension:
* 100% Local Storage: All data lives exclusively in your browser.
* No Accounts Required: No sign-ups, no tracking, and no third-party servers.
