FocusLock review
Free desktop blocking with recurring schedules, strict modes, and local focus analytics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FocusLock is a free, open-source distraction blocker for Windows and macOS. It is designed for people who want to restrict both distracting websites and desktop applications from one app. Website blocking works at the operating-system DNS level, while application blocking targets processes by name. Users can create focus profiles and category block packs, start timed sessions, configure Pomodoro work and break intervals, and set daily goals. The app does not require an account, and optional app-usage tracking is stored locally on the device.
Its strongest fit is scheduled, repeatable focus work. Recurring sessions use cron syntax, giving technically comfortable users detailed control over when blocks run. Hardcore Mode is intended to prevent early session termination, while Friend Lock adds accountability-based unlocking. Focus analytics include streaks, goals, heatmaps, achievements, and focus intentions, so the product covers both enforcement and progress tracking. The combination of DNS blocking and process-name blocking also makes its scope broader than a browser-only blocker.
FocusLock is particularly suitable for technical users who want free locking tools without a subscription or account requirement. Its main trade-off is platform and ecosystem coverage: it runs on Windows and macOS, but has no mobile apps and no browser-extension support. Administrator access is required, and cron syntax may be less approachable than visual scheduling controls. Choose FocusLock for desktop-wide website and application blocking, recurring sessions, strict locking, and local analytics. Choose an alternative if mobile coverage, browser-specific controls, or a simpler scheduling interface matters more than open-source desktop control.
