Online Alarm Clock
Set alarms that ring in your browser.
What is the online alarm clock?
Our online alarm clock rings at a time you set, running entirely in a browser tab. You can set as many alarms as you need; each one runs on its own schedule and saves in this browser. If you register to the website, the list follows you across devices.
How to use the online alarm
Tap "Set Alarm", pick a time, save. The preview tells you when it'll fire ("Tomorrow 7:30 AM, 8h 12m from now"). Dismiss or Delay when it goes off. The preset buttons above are shortcuts for common wake hours. Also, from the settings, you can change the time format and the volume.
Why use an online alarm clock?
Phone's charging in the kitchen and the laptop's on the nightstand. Or you're napping, and don't want to fumble for the phone. Or a long video call where a wrap-up cue keeps you on time. An online alarm clock runs in any browser tab and rings on schedule, no separate device required.
Common questions
- Will the alarm ring if I switch to another tab?
- Yes. As long as the browser tab stays open, the alarm fires at the set time.
- What happens if my laptop goes to sleep?
- The browser pauses with the device, so the alarm can't ring while the computer is asleep.
- Can I set more than one alarm?
- Yes. Add as many as you need. Each runs on its own schedule.
- What time zone does the alarm use?
- Your device's local time. The alarm follows the device across time zones, not the zone you set it in.
- Will my alarms survive a refresh or a closed tab?
- Yes. Alarms save in the browser. If you sign in, they save to your account and follow you across devices. But when you refresh the page or return to it from another device, you need to click somewhere on the page for the alarm to sound.
