Automatic focus mode for people who actually want to get work done.
Forca detects when meetings end and automatically starts your focus zone — blocking distractions instantly. No manual switching, no excuses, no friction.
Meeting Ends
Your calendar event finishes and Forca detects the change.

Sites Blocked
Distracting websites are blocked across all browsers.
