Chrome: We've all been there: Popped onto a site "just for a few minutes" only to emerge hours later to find your day gone. Rather than completely block sites so you can't use them at all, The Productivity Owl Chrome extension lets you surf a site for a short period before kicking you off.
This is useful if you often need access to potentially time-sucking sites. The owl waits in the background as soon as you go to a website and gives you just enough time to read what you need before it closes the tab.
Although the owl is very strict, you can customise how it works. For example, you can set how much browsing time you're given, which sites should never be closed and which to always block, and schedule free time during the week when you can browse any pages. During those free times, you can access sites the owl prevented you from visiting but saved for later.
The Productivity Owl also gives you a score for how well you follow the program. Mostly, it's a very motivating extension that forces you to quickly get the information you need and stop lingering or procrastinating. Do you dare try to ride the owl?
