It's great.

I use against bad habit, time consuming websites. Simple and effective! Thank you for all contributors

Great add-ons!

I was struggling with managing my time online. And this extension helps me a lot doing just that. Thank you.

An amazing tool to boost your productivity. Also simple to use =)

My God, I hate the access codes so much. It's perfect, thank you so much!!

Has every feature you can think off. Super glad I've got it. Not sure if I'm doing it wrong but it would be great to be able to set a block past midnight (2000-0200) for example. cheers for making this free.

Doubled my productivity

Near perfect, however I wish that moving a set meant that all it's information (start date data, time spent since start data) that's in the statistics menu moved with the set when it's moved up or down in the list.

I like the feature: " Enter a time limit after which to block these sites (optional): "

This single extension helped me go from a 2.4 GPA student to a 4.0 and top of my college class in Statistics, Computer Science, and Math!

Es una aplicación sencilla pero muy eficiente, hace lo que se supone que debe hacer de una forma fácil y sencilla. Si me ha ayudado a concentrarme, creía que iba a ser inutil pero si me ayudó.

Quite Useful

Works perfectly after some tinkering

Great extension! I would recommend adding the ability to block/allow based off website tab titles, as there are some use cases involving Youtube that I could make use of :)
