Pause, Resume & Reset

Full control over your sessions. Pause when interrupted, resume when ready, or reset to start fresh.

Task Naming

Label each session with what you're working on. Stay intentional about where your focus goes.

Session Stats & Streaks

Track total sessions completed, focus minutes logged, and daily streaks. See your completed task history with timestamps.

Smart Notifications

Audio alert and Chrome notification when your session ends. Visual progress ring counts down in real time.

Dark Side-Panel UI

Runs in Chrome's side panel with a dark interface that stays out of your way. No popups, no new tabs.

Lock In and Get It Done

Lock In Timer lives in Chrome’s side panel — always accessible, never in the way. Whether you use the Pomodoro Technique, time-blocking, or your own focus method, it adapts to how you work.

Who It’s For

Students cramming for exams. Developers deep in a codebase. Writers hitting a deadline. Anyone who wants a distraction-free timer that just works, without signing up for yet another productivity app.

What’s New in v2.0

Version 2.0 is a major upgrade: pause and resume support, a reset button, custom timer lengths, persistent state that survives closing the panel, full session statistics with daily streaks, and Chrome notifications so you never miss a timer — even from another tab.
