Tools to block websites

Any recommendations for a tool to help block websites (preferably with a whitelist) for a certain amount of time?

I.e. hit “Stop me faffing about dammit!” button and it blocks all but a handful of white-listed sites for an hour.

I’ll put together all options in a sheet and share, but any recommendations?

One feature I am looking for (seen it somewhere previously I am sure but can’t find it now) is an “emergency unlock” where you can unlock it, but its a pain. Maybe something like inputting a big number or a “Are you sure, you can confirm you’re weak in 60 seconds” dialog.

I’m liking Focus ( for this. Really, really flexible and configurable.

Anything for those of us on Windows?

RescueTime is a mess from a UX perspective, but it works well once you get
the hang of it.

Cold Turkey works well, but the user interface is a little strange and there are some bugs.
I’m reasonably satisfied with it, though, and I’ve been using it for years.

Cold Turkey did not work for me at all. The sites are just not blocked. May be it is because I use a proxy (corp environment)?

Oh, I see:

The process cannot access the file 'C:\Windows\system32\drivers\etc\hosts

In my corp environment that file is not accessible for regular users.

P.S. The author should really be invited over here – I believe he/she’d benefit from providing a trial for the Pro version.

You can have a try on cisdem app crypt to block websites or apps.
