About Alarm Clock
Need a reminder to step away, take a call, or wake from a quick nap, but your phone is across the room? An online alarm clock lets you set a time right in your browser and plays a sound when it goes off, no app required.
Just choose the time you want the alarm to ring and leave the tab open. When the moment arrives, the alarm sounds to grab your attention. It is free, starts instantly, and there is nothing to install. Use it as a desk reminder, a timer for the oven, a nudge to end a break, or a backup wake-up. As long as the tab stays open, the alarm is ready to go off.
