FocusBlock

FocusBlock is not another site blocker with a fixed schedule. It learns when you actually do your best deep work and automatically protects those windows — no manual configuration required.

During its first week, FocusBlock runs silently in the background, logging when you visit focus-disrupting sites (social media, news, YouTube) and correlating that with your calendar events and typing activity. After 7 days it builds a personal focus profile and starts automatically enabling blocks during your high-productivity windows.

Core features

• Adaptive scheduling: blocks adjust automatically as your routine changes
• Calendar integration: knows when you are in a meeting vs. doing deep work
• Commitment mode: optionally lock blocks so you cannot disable them mid-session
• Focus stats: weekly report showing your distraction patterns and improvement over time

Available for macOS, Windows, and as a Chrome/Firefox extension.
