What is an Online Alarm Clock?
An online alarm clock is a free digital tool that lets you set alarms directly in your web browser—without needing to download an app or buy a physical alarm clock. It works on any device—desktop, laptop, tablet, or smartphone—and plays a loud sound at your chosen time to wake you up, remind you of tasks, or keep you on schedule.
Unlike traditional alarm clocks, an online alarm clock is accessible anytime, anywhere, requires no installation, and can be customized with multiple sounds, snooze options, and timers.
