Helps block distractions, relaxes and reduces stress, increases focus while enhancing privacy, soothes migraines and headaches, and masks ear ringing.
SelfControl is a free and open-source application for Mac OS X that lets you block your own access to distracting websites, your mail servers, or anything else on the Internet. Just set a period of time to block for, add sites to your blacklist, and click "Start." Until that timer expires, you will be unable to access those sites--even if you restart your computer or delete the application.
Block an unlimited number of websites using timers and enable statistics to keep track of the biggest time-wasters.
