FocusLock

What FocusLock is

FocusLock is a free distraction blocker for macOS and Windows that blocks websites and apps at the operating-system level. It uses the OS hosts file to block sites across browsers, without extensions or separate browser setup, and blocks apps by process name with a check every two seconds. Focus sessions can use Hardcore Mode, which cannot be ended early, or Friend Lock, where a trusted person can unlock the session with a token. A configurable Pomodoro timer and recurring schedules written in cron syntax support planned sessions. Focus profiles, session history, block lists, statistics, and settings are stored locally. Optional per-app usage tracking is off by default, saves samples in a local SQLite database, and deletes those samples when disabled. The privacy policy says FocusLock has no crash reporting or day-to-day activity tracking. Update checks send the operating system, CPU architecture, and app version to the update server and GitHub API; the policy says IP addresses are not logged or stored. The source code is public under GPL-3.0. FocusLock is described as a voluntary productivity tool, not a parental control system or a sole means of restricting content.
