Timers, stopwatches and alarms aren't all that exciting, but the apps that combine all of that functionality into one simple, beautiful interface are surprisingly few and far between.
Timer tab does just that, and it has just the right amount of features to make it a surprisingly great app. The interface is simple: a timer on the left, alarm in the center, and stopwatch on the right. Click one, set it, and forget it. From the app itself, or the Chrome extension, the settings allow you to change the background to any image on the web, set a YouTube video for the notification, or allow notification popups. The tab itself will also display relevant info, making it a handy pinned tab, and will turn red when appropriate (when the alarm or timer is finished, for example).
That's all the app does, but it does it all well.
