Free Online Alarm Clock
Set one or more alarms right in your browser — no app, no account, and no notification permissions to configure. Each alarm repeats daily at the time you set, and you can add an optional label so you always know which one just went off.
How to Use It
Choose a time, optionally give it a label like "Wake up" or "Stretch break," and press Add. Your alarm appears in the list below, where you can flip it on or off with the toggle or remove it entirely. When an active alarm's time arrives, the screen flashes and an alert tone plays until you press Dismiss.
Because this alarm runs entirely in your browser, it can only ring while the tab stays open — closing it or shutting your laptop will stop the countdown. For anything time-critical, pair it with your phone's built-in alarm as a backup.
Tips & Tricks
Stack alarms for a routine. Add several labeled alarms — "Leave for gym," "Lunch," "Log off" — to structure a whole day without checking the clock repeatedly.
Turn alarms off instead of deleting them. The toggle switch keeps a recurring alarm saved for tomorrow without needing to re-enter the time.
Use 24-hour entries carefully. The time picker follows your browser's locale settings, so double-check AM/PM if your browser displays a 12-hour clock.
Frequently Asked Questions
Do alarms repeat every day?
Yes. Any alarm that's toggled on will trigger at that time every day the tab is open, until you turn it off or remove it.
Will the alarm work if I close the tab?
No. Like most browser-based timers, it needs the tab to remain open to keep checking the time and play the alert.
Can I set more than one alarm?
Yes. Add as many as you need — each one is tracked and triggered independently.
