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 iOS device, which are then synchronized across your iOS and macOS 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.

To help you stick to your rules about:blank has an option that requires you to enter a random string to delete existing rules.

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

Exactly what I wanted!

This app, unlike other “blocking” apps, allows you to drill down to specific web pages to block those without affecting the rest of the site. Perfect for if I want to isolate only certain parts of a site without having to block off the whole thing. I love it! It also has a video demonstration for how to use the app to generate the URL you want to block instead of copy-pasting and escaping all the special characters manually. It’s great!

Does exactly what it says

Wanted to stop constantly checking the news on my phone. Typed in the websites. Boom. It blocked them. Works perfectly for my needs.

Wish it had the option of longer strings!

This app has a cool feature where You can set it so that you have to type in a string of random numbers before you can access the website. I think this is a really cool idea, but I wish I was an option to increase the length of the random’s trying to say, 500 digits, to make it a real dissuasion from visiting my favorite dish rafting websites like Reddit or Instagram
