about:blank is an app that blocks websites in Safari . I use it to break my bad browsing habits and to stay productive.

You specify the websites that you want to block on your mac or iOS device, which are then synchronized across all your other devices.

The rules are based on regular expressions, which allows for fine control over a blocked URL. For example you can block the landing page of YouTube and still watch individual videos.

Furthermore you can block websites on the fly inside of Safari .

Simple and effective

After searching around for a way to block facebook, I almost gave up because I couldn’t find a simple safari extension to do so. All of them made you set a time limit or had more features than I needed. This app easily allowed me to do it without a bunch of bells and whistles. Highly recommend.

simple and effective -- works well

It took me a couple of tries to understand how to turn it on -- I think the key is restarting Safari -- but then once I found the little a:b button it was easy to use to block a couple of sites that are my biggest time-wasters. Thanks!

Have to pay twice to get app to work

It appears you have to pay for ios app after paying for mac app to get this to work right. Why do I have to pay twice? That is a very frustrating purchase.

Developer Response ,

You are not required to own both apps for it to work. Each app works independently of each other.

Please reach out to me through so I can help you figure out what went wrong.
