Online Alarm Clock

Turn this browser tab into a loud, reliable alarm clock. Pick a time or start a quick 10, 20 or 45 minute timer, choose from three sounds, and use the 5-minute snooze when it rings — completely free, no signup needed.

How to use

1. Pick a time or press a quick timer (10/20/45 min), then Set Alarm.
2. Use Test Sound first to check that the volume is right.
3. The alarm will ring on time — press Stop or Snooze.

Tips

• Press Test Sound before setting the alarm — browsers start muted sometimes.
• Keep the tab open and stop your device from sleeping, or the alarm will not ring.
• Quick timers are perfect for power naps, cooking and study breaks.

Important: keep this tab open and do not let your device sleep, or the alarm will not ring. Keep the volume high.
