About
A little distance from distraction.
Blocker is a Mac app that turns off the websites and apps you pick, so staying focused takes fewer decisions.
One block, across your Mac
Use Blocker when you want distracting sites blocked across browsers and distracting Mac apps kept closed. Start a session right now or schedule recurring hours for work, study, or a personal project. Your blocklist and schedules stay on your Mac, and blocking works offline.
Off, Strict, and Hardcore modes let you choose how difficult it is to stop early. They have different rules and exceptions; the lock-mode FAQ explains them. Blocker also tracks streaks, focus hours, and distractions blocked.
Built by Léo Mathurin
Blocker is made by Léo Mathurin, an independent developer. You can get in touch for help with the app, a purchase question, or feedback about what should improve.
The changelog records published updates. The Mac blocker comparison includes setup checks and trade-offs to help you decide whether Blocker suits your needs.
Try it on your own setup
Blocker is available for macOS 14 or newer with a full-featured 7-day trial, followed by a one-time licence. Check the current price before buying. Windows is planned; the Windows waitlist is open.
No app account is needed. Local blocking does not mean there is no analytics collection: the privacy policy explains product analytics, crash reports, and how purchases and waitlists are handled.
