What is Xclock?
Xclock is a fullscreen clock, timer, stopwatch, alarm clock, and sleep timer that runs in your browser.
No downloads or accounts required.
Timer
- Select a duration, then start the timer.
- Use named timers to run multiple small timers independently.
Alarm
- Set an alarm time and optionally give it a label.
- Use snooze and stop controls when the alarm rings.
Stopwatch
- Start/stop/reset the stopwatch for workouts, cooking, or study sessions.
Sleep Timer
- Set a sleep timer to stop or alert after a selected duration.
Troubleshooting
- No sound? Increase device volume and make sure your browser tab is not muted.
- On iPhone/iPad: some sounds require a tap interaction before audio can play.
- Not fullscreen? Use your browser fullscreen mode (usually F11 on desktop).
