Set a free online alarm right in your browser - No app and no sign-up. Pick a ready-made time below, or use the alarm above to choose any time you like. When the moment comes, your alarm rings with sound, even if you switch to another tab.

Choose the alarm by job

Need more than a preset time? Use a wake-up alarm for mornings, a meeting reminder alarm for calls, a school alarm for classes, or a work alarm for deadlines and breaks.

💡 Tip: Heavy sleeper? Set two alarms a few minutes apart - For example a 7:00 AM and a 7:15 AM backup.

How to set an alarm in 3 steps

Start with a preset or choose your own time

Preset alarm pages are useful for common wake-up times, work reminders, and short breaks. If the preset is not exact, adjust the hour and minute before you activate it.

  1. Pick a time. Choose a preset from the lists above (like a 6:00 AM alarm) or set your own.
  2. Add a label (optional). Name it "Wake up" or "Meeting" so you know what it's for.
  3. Keep the tab open. Leave Alarm.now open and the alarm will sound at the right time.

Why use an online alarm?

Good for wake-ups, reminders, and timed routines

An online alarm is best when you are already working in a browser and want a clear sound alert. For longer work blocks, pair it with a 25-minute timer or the multi-timer.

  • Always with you: works on any computer or phone with a browser.
  • Loud and clear: plays a sound and shows a pop-up when time is up.
  • More than wake-ups: great for reminders, breaks, cooking and study.
  • Pairs with our other tools: try the 10-minute timer or stopwatch too.
