An operating-layer focus controller that makes distraction structurally impossible. Always running, always enforcing, always calm.
macOS 14+ · Free forever for Baseline mode · No account needed
Three Modes
Always active. Your deny-list of distracting apps and websites is enforced 24/7, no session needed. The machine is always shaped for focus.
Expanded blocking on top of Baseline. More apps blocked, easy exit when you need it. For everyday focused work.
Allow-list mode. Only your chosen apps may run — everything else is terminated. Hard exit. Your Ulysses Contract with focus.
Built Different
Apps are terminated at the process level. Websites blocked via system DNS. No browser extension needed. Works everywhere.
25, 50, or 90-minute sessions with countdown — or go open-ended. Auto-ends when time is up.
Track consecutive focus days. Earn streak freezes. Level up from Beginner to Grandmaster across 20 levels.
Launches at login. Lives in your menu bar. Baseline mode blocks your worst apps 24/7 without you thinking about it.
Warm dark palette, spring animations, SF Pro typography. Designed to feel like Raycast, not a 2009 utility.
Sessions survive app crashes and reboots. Heartbeat monitoring detects failures. Your focus is never accidentally broken.
"Focus should not depend on willpower. The environment should make distraction structurally difficult."
