Beautiful design, simple to use. Really helps with reducing wasted time each day.

It works.

Take back control of your life! This little Add-on is perfect to make you realise how much time you spend on sites and helps you trim the fat and get back hours of your time.

Well designed and unobtrusive. Helps me be aware of my time commitments.

There are sometimes a few bugs with websites not being properly blocked when there are many tabs of the same website, but other than that, an excellent extension!

This beats blockers because it actually trains you to not waste time rather than just blocks stuff you inevitably unblock.

I have tried many browser addons that claim to help you focus or block distracting sites. This is the most thoughtfully designed (and effective!) extension I've ever used. Highly recommend!

Great extension, I only wish I could set different timers for different groups of sites.
