Site Block Pro is a free and powerful Chrome extension developed by zensiveapp to help users boost focus and reduce digital distractions. With flexible website blocking capabilities, users can choose to block sites outright or set custom policies. The extension also offers schedulable restrictions with daily time limits, password-protected settings, and a unique "Stay Still" challenge to resist browsing urges.

Additionally, Site Block Pro provides insightful usage statistics and charts to track online habits. The new whitelist feature allows users to specify URLs or paths that should always be allowed, even when the main domain is blocked. This feature enables users to access specific content within otherwise blocked domains, promoting productivity and focus.
