Contest Clocker v2 v2.7: Our Journey So Far

Source: Dev.to

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.

🚀 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 Google Calendar or Outlook calendars, with auto‑sync via Google Sign‑In.
• Smart Notifications – Custom reminders at 15 minutes, 1 hour, or 1 day before contests; now also includes daily challenge reminders.
• LeetCode Daily Challenge Tracking – New card 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 (12/24 h), high contrast, and more.
• Advanced Filters – Filter by 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
