About Alarm Clock Tab

Alarm Clock Tab is a free online alarm clock for people who want a simple way to wake up or remember a task without installing an app. It runs in a browser tab, so you can keep it open on your computer while you work and set an alarm for a chosen hour and minute.

When the alarm goes off, a message appears on screen and the alarm sound plays, so the reminder is easy to notice. The page also offers preset alarms for quick reuse.

Beyond the alarm, the site bundles several related tools in one place, including a timer, a Tabata timer, a Pomodoro timer, a stopwatch and a time zone calculator. That makes it a practical all-in-one clock for everyday timing and focused work sessions.
