macOS menu bar app
One click.
Locked in.
Focus profiles that open your apps, arrange your windows, kill distractions, and start a timer. One button.
Three steps. That's it.
Create a Profile
Pick which apps to open, how to arrange them across desktops. Name it and save.
Click Start
Lock It opens your apps in the exact layout, closes everything else, activates grayscale, and starts the timer. You're in the zone in seconds.
Stop & See Your Stats
When you're done, stop the session. Lock It saves your focus time, tracks your streak, and shows you exactly how much deep work you've done.
Built on how your brain actually focuses.
Not a productivity hack. Designed around real research on attention, habits, and deep work.
Setup friction kills your focus before it starts
Research from UC Irvine shows it takes 23 minutes to refocus after a context switch. Every time you manually open apps, arrange windows, and close tabs — you're burning cognitive energy before the real work begins. Lock It removes that friction. One click and your workspace is ready.
Your environment decides what you do
Behavioral psychologists call it choice architecture — the space you're in shapes your behavior. A desktop with Slack, Twitter, and email open is built for distraction. Lock It restructures your screen. It closes what doesn't matter and places only the tools you need in front of you.
Color keeps you hooked to the screen
Studies from the Center for Humane Technology show that color triggers compulsive screen use. Removing it cuts the dopamine loop that pulls you toward distractions. Lock It activates grayscale automatically when a session starts. Your screen becomes a tool, not a trap.
Rituals build flow
Mihaly Csikszentmihalyi's research on flow states shows that consistent pre-work rituals train your brain to focus faster. The same setup, same trigger — your brain learns that when Lock It activates, it's time to work.
Tracking what you do changes what you do
The Hawthorne Effect: measuring behavior improves it. When you see your focus streaks, total hours, and session history, you naturally push to stay consistent. Lock It tracks every session — time, streaks, per-profile stats. Your deep work becomes visible.
