Alarm Timer Stopwatch Chrome extension

Alarm Timer Stopwatch adds multiple alarms, countdown timers, and stopwatches to your browser, with snooze options built in. It's best for people who want simple time-tracking tools without leaving Chrome. The catch: alarms only work while your browser is open, so it's not a replacement for a phone or system alarm.

What Alarm Timer Stopwatch does

Alarm Timer Stopwatch combines three time-tracking tools in one browser extension: alarms for scheduled reminders, countdown timers for tracking a set duration, and a stopwatch for measuring elapsed time. You can run multiple alarms or timers at once, which suits people juggling several tasks with different time limits.

Alarm Timer Stopwatch free vs paid

The extension is free to install and use, with no listed paid tier. All three tools — alarms, timers, and stopwatch — are available without a subscription or upgrade prompt.

Is Alarm Timer Stopwatch safe?

As a time-tracking tool, it doesn't need to read the content of the pages you visit to function, since alarms and timers run independently in the browser. Keep in mind that because it's browser-based, alarms will only fire while Chrome is open and running.
