- Start: Click the 'Start' button to begin countdown
- Pause/Resume: Pause and resume as needed

FAQ
The timer doesn't seem accurate
When browser tabs are in the background, browsers slow down timers for performance optimization. Keeping the timer tab active (in foreground) improves accuracy.
I can't hear the alarm sound
Check if your browser or system volume is muted. Some browsers may not play sounds without user interaction (clicks, etc.).
Can I save or export lap times?
The current version only displays lap times on screen, and they disappear on page refresh. CSV export functionality is planned for future updates.
Can I run multiple timers simultaneously?
Currently, you can only run one timer or stopwatch at a time. If you need multiple timers, open multiple browser tabs and run one in each.
Can I use this on mobile?
Yes, it works normally on mobile browsers (Chrome, Safari, etc.). However, the timer may stop if your mobile device enters power-saving mode, so keep the screen on or disable power-saving mode.
