Chrome: How productive are you, really, when you're online? Unless you track your time, you might not really know. Limitless is a new extension that not only tracks your browsing habits, it also inspires you to complete your goals.
Every time you open a new tab, Limitless greets you with a productivity tip, a pleasant background and how much time you've spent on different site categories. You can edit sites' categories in case you want to put Lifehacker into entertainment rather than productivity, for example (but you wouldn't do that, would you?). When you first set the extension up, you tell the app your goals for the new year and can also add a daily goal, to be reminded of these when you open a new tab.
Limitless also displays how long you've been on a productive or time-wasting site with a green or red number in the icon.
If you tend to get really distracted, you'll probably need a more powerful site blocker, but for everyone else, this is a helpful tool, much like RescueTime, but for your browser. A Firefox version is in the works.
