Timer Tab is a free application offered through the Chrome Web Store and as a stand-alone website at timer-tab.com. As a Chrome app Timer Tab can be used online or offline. The website version of Timer Tab can only be used online. Both versions of Timer Tab offer a count-down timer, an alarm clock, and a stopwatch. For the count-down timer and the alarm clock you can select a video to play when time expires or when you’ve reached your specified alarm time. You do this by pasting the url of a YouTube video into the “alarm” field below the timer. Also in both versions of Timer Tab you can customize the background by specifying an image url.

Applications for Education
I often use a countdown timer in my classroom to time activities and to time breaks between activities. I find that using a timer helps me and my students maintain our focus better than if we just used a clock without an alarmed timer. Timer Tab could be a handy little timer tool that you can use anytime you have your laptop with you.
