What is an Online Alarm Clock?

An online alarm clock is a web-based application that allows you to set alarms directly in your browser without downloading any software. Unlike smartphone alarm apps, a browser-based alarm clock works on any device with internet access - your laptop, desktop, tablet, or even smart TV. It's perfect for people who work at their computers, students studying at their desks, or anyone who prefers not to rely solely on their phone.

Our free online alarm clock offers features that rival dedicated alarm apps: multiple alarms, customizable sounds, snooze functionality, and repeat options for daily, weekday, or custom schedules. Browser notifications ensure you never miss an alarm, even if you're browsing another tab.

How to Use This Alarm Clock

  1. Add a new alarm - Click the "Add Alarm" button to open the alarm editor. Set your desired time using the hour and minute selectors.
  2. Name your alarm - Give your alarm a label like "Morning Wake Up," "Take Medication," or "Meeting in 30 min" to identify it at a glance.
  3. Choose a sound - Select from available alarm tones. Click "Preview" to hear it before saving.
  4. Set repeat options - Choose "Once" for a one-time alarm, "Daily" for every day, "Weekdays" for Monday-Friday, "Weekends" for Saturday-Sunday, or "Custom" to select specific days.
  5. Enable browser notifications - When prompted, allow notifications so your alarm will alert you even if the tab is in the background.
