Chronos Timer

About

Chronos Timer is a powerful, elegant multi-timer extension for Chrome that lets you create, manage, and group countdown timers without ever leaving your browser.

➤ ✨ Key Features

✓ Multiple Timers, Zero Friction
Create as many countdown timers as you need. Each timer runs independently — start, pause, and reset with a single click.

✓ Timer Groups
Organize related timers into named groups (e.g., "Pomodoro Cycle", "Morning Routine", "Meeting Buffer"). Launch all timers in a group simultaneously or with staggered starts.

✓ Staggered Group Launch
Configure offset delays when launching a group so timers start sequentially instead of all at once — perfect for structured workflows.

✓ Side Panel Support
Keep timers visible while you browse. Open Chronos Timer in Chrome's native side panel so it stays docked alongside your web content.

✓ JSON Backup & Restore
Export all your timers and groups as a JSON file for backup or transfer. Import from any previously exported file to restore your setup instantly.

✓ Premium UI — Dark & Light Mode
Toggle between a sleek dark theme with glassmorphism effects and a clean light mode. Smooth animations and modern typography (Outfit + Inter) make every interaction feel polished.

✓ Persistent Timer State
Timer state survives popup close and browser navigation — your timers keep ticking in the background thanks to `chrome.alarms`.

✓ Desktop Notifications
Get notified the moment a timer finishes, even when you're focused on another tab.

✓ 🎯 Perfect For
- Pomodoro / deep work sessions
- Meeting time management
- Cooking and exercise routines
- Any activity that benefits from structured time blocks

✓ 🔒 Privacy First
Chronos Timer stores all data locally on your device using `chrome.storage.local`. No data is ever sent to any external server. No analytics. No tracking. See our full privacy policy for details.
