Replay - Watch Time Tracker од Ricardo Moura

Replay is like Steam playtime, but for YouTube. It quietly tracks how much time you actually
spend watching - then shows you the full picture in a clean dashboard.

What you get (all free):
- Watch time per channel - a ranked leaderboard of where your hours really go
- Breakdown by category (and game, on Twitch - coming soon)
- A GitHub-style activity heatmap of the last year
- Daily & weekly trends, streaks and active-day counts
- Local insights: most active day, busiest weekday, channel of the month, and more
- Daily & weekly limits with a friendly notification when you go over
- Export everything to JSON or CSV anytime

Built to be trustworthy:
- Accurate - it ignores ads and paused video, and won't inflate your numbers
- Private - no account, no servers, no tracking. Your data never leaves your browser
- Yours - exclude channels, skip Shorts or music, pause tracking whenever you like
