Sigmund is a website blocker that you can use to stop yourself from wasting time on Reddit, news sites, Facebook, and so on. Give yourself a set amount of time each day, and spend up to that time procrastinating; then, you'll have to focus!
You can also sign up for notifications in the Preferences menu to keep an eye on how much longer you can procrastinate. At 4:00 each morning, your remaining time will reset.
(Sigmund is inspired by Monastery, but with more clear licensing, less permissions, and less power usage.)
