Install in three steps

  1. 1

    Open the file

    Open FocusLock-0.4.2-….msi from your browser's downloads or your Downloads folder.

  2. 2

    If Windows asks, allow it

    Early access builds aren't code-signed yet, so Windows may show "Windows protected your PC". Select More info, then Run anyway.

  3. 3

    Start focusing

    Open FocusLock from the Start menu. A short setup helps you choose your learning sites and study browser.

What's new in 0.4.2

Released 8 October 2026

Pick up where you left off, and finish when you are ready.

New

  • Finish when you're ready: the break screen shows how many focus periods you've done and offers Finish session. One click ends the session as complete, and every focus period you did counts in full. No more endless focus and break cycles.
  • Finish after this focus period: from Leave, during a focus period, you can choose to stop when the current period ends. The timer bar shows "Last focus period". Change your mind any time with Keep going after this period.
  • Continue what's already open: if a course video or lesson is already open in your study browser when you start, the session continues right there instead of opening a new window. You can turn this off in Settings.

Fixed

  • The Leave session button on the break screen now works, and session dialogs always stay on top of the break screen.
  • Releasing the "hold to leave" button early now shows a hint instead of looking like nothing happened.
