Contest Clocker v2 v2.7: Our Journey So Far

Competitive programming is about consistency, preparation, and timing. That's exactly why we built Contest Reminder, a browser extension to help developers never miss another coding contest again. From version 2.0 to the now fully-featured 2.7.7, we’ve evolved fast — and entirely in production.

Here’s a look at how we’ve scaled the product in public, added user-loved features, and what’s coming next.

🚀 From Version 2.0 to 2.7.7 Highlights
✅ Core Feature Growth

  • Multi-Platform Contest Tracking: Started with Codeforces, CodeChef, and LeetCode — now includes AtCoder, HackerRank, and TopCoder.
  • Calendar Integration: Users can instantly add contests to their Google Calendar or Outlook calendars. Now supports auto-sync via Google Sign-In.
  • Smart Notifications: Custom reminders at 15 minutes, 1 hour, or 1 day before contests — now with daily challenge reminders too.
  • LeetCode Daily Challenge Tracking: A new card allows users to view and mark daily problems, featuring auto-reminders and streak retention.
  • Daily Streaks: Timely nudges to keep users engaged every day.

⚙️ UI & Experience Enhancements

  • Platform Reordering: Users can choose how platforms appear.
  • Configurable Layouts: Font size, columns, time formats (12/24h), high contrast, and more.
  • Advanced Filters: Platform, contest type, duration, and uncategorized contests.
  • Dark/Light Modes: Minimal, clean glassmorphism design with smooth toggles.
  • Share Button: Users can copy or share contests easily with others.

⚡ Performance & Reliability

  • Data Fetch Optimization: Fetch only enabled platforms, use long-lived caches.
  • Rate Limited Refresh: Prevents API overload by limiting user-triggered refreshes.
  • Fallback Handling: Clear error states for each platform if down or blocked.

✨ Premium-Ready Infrastructure

  • Google OAuth integration
  • Calendar auto-sync behind sign-in
  • Support and donation prompts via BuyMeACoffee
  • Email display for signed-in users

🎨 New (upcoming)

  • Added two stunning themes — Matrix and Batman.
  • Theme engine refactored for better performance and customizability.
  • WebP optimization saves 830KB in theme assets!

💬 What’s Next?
