Online Alarm Clock FAQ
Use this online alarm clock as a free web alarm clock, browser alarm, wake-up alarm, meeting reminder, medicine reminder, or quick daily alert. It runs in the browser, supports sounds and snooze, and works best when the tab stays open.
How to use
- Check the current time shown in the browser
- Choose the alarm hour, minute, sound, and name
- Use the sound test to confirm volume and browser audio permission
- Set the alarm, keep the tab open, and use snooze or stop when it rings
Examples
Wake-up alarm
Save 07:30 as a quick preset so the next alarm takes one click on mornings when the browser is open.
Meeting reminder
Name a fixed reminder time, test the sound, and use snooze if you need a short delay before joining.
Medication or cooking alert
Create a simple browser reminder for a specific time without installing a separate alarm app.
Can I use this as an alarm clock online?
