13 Best Free Website Blocker Apps for
Boosting Your Productivity (2020)

How often do you check your email or phone notifications in the midst of doing work? So often it’s embarrassing to count? Yeah, we thought so.

Now, if you’re wondering why you’re struggling to get things done and why you’re not your most efficient self at the office, then it’s very likely the fault is in the little, “innocent interruptions” of checking email or Facebook at work.

We tend to excuse this behaviour, as it’s often only a few 5-10 minutes of “taking a break”, but the true cost of it is quite devastating. Studies show that every time you check your phone, email or social feed and then return to your work, this switching from one task to another causes your focus to drop, a phenomena called “attention residue”, as introduced by Cal Newport in his bestselling book “Deep Work”. In fact, your mind requires about 23 minutes to re-focus and get back to work, fully-focused on the task at hand. That’s a lot of time to lose, and a lot of money.

While there are many roundabout ways to fix the productivity issue, the most immediate solution is simply – stop browsing web. Like for any problem there’s a problem-solving product. So here’s our ultimate list of 13 best website blocker apps that will help you avoid distractions for enhanced office productivity.
