Less Sit.
More Fit.
FitLock is a macOS app that seals your entire screen every 30 minutes until you complete a real exercise. Not a notification. A lockout.
macOS 26+ · Apple Silicon · Zero telemetry
“Hands down. Twelve clean reps, full depth. Move.”
Eight hours at the desk. Barely moved.
Long days hunched over a screen, one position, no movement — and the usual fix is a notification you can swipe away in half a second. That changes nothing. FitLock removes the option: the screen seals, the timer holds, and the only way out is through the movement.
Three steps. No easy out.
Sits in your menu bar
A single icon and a live countdown. FitLock runs silent and meeting-aware, waiting for the next cadence to fire. Nothing to manage.
Seals every screen
When the timer hits zero, the lockdown drops. All displays sealed, hazard edges lit, countdown holding. There is no dismiss button.
Move. Get released.
Complete the exercise, the lock falls away, your streak ticks up. Back to work — until the next one fires. The only way out is through it.
Watch a lockdown fire.
Idle in the menu bar → the timer hits zero → the lockdown seals every display → you move → released. On a loop.
On the wall. Thighs parallel. Hold it. Do not drop.
DEACTIVATED
Six coaches. One job.
Your coach sets the tone — and the difficulty. The ladder climbs from relentlessly cheerful to genuinely brutal. Tap one to see how they run your lockdown.
"On the wall. Thighs parallel. Hold 45. Brace. Do not drop."
Sarge doesn't ask, Sarge tells. Clipped commands, zero small talk, and a deadline that was already over. You have reps to do — move.
Out of sight. Until it strikes.
A native macOS app that hides in your menu bar — sleek, silent, almost invisible. Just an icon and a countdown, until the timer runs out and it takes the whole screen.
Built to be unignorable.
Full-screen containment
Seals every connected display at once. No app stays on top of FitLock.
Six distinct coaches
From cheerful Sunny to brutal Drago. Each has their own voice — and sets how hard your targets start and ramp.
Your cadence
Fire every 30, 60, 90 minutes — or as little as once a day. Set the active hours and days it's allowed to seal.
Meeting-aware deferral
Notices when you're on a call — mic or camera in use — and holds the lockdown until you're free.
Streak tracking
Every cleared lockdown ticks your streak. Miss one and it resets — keeps you honest.
Targets that ramp
Your coach sets the starting difficulty and quietly raises it over time, so it never stays easy.
The fine print.
There's an Emergency Release button for the moments that genuinely can't wait — you'll never be trapped. But it's deliberately the boring option: you skip the movement, break your streak, and crawl back to your chair having proved the chair's point. The whole app exists to get you to do the thirty-second exercise instead. Use the escape hatch if you must. We'll both know.
FitLock watches for an active microphone or camera and holds the lockdown while you're on a call or screen-sharing, then fires once you're free. It's good, not psychic — odd setups can slip past it. If one ever fires at the wrong moment, you're one click from off: just toggle FitLock down in the menu-bar app.
Never. FitLock runs entirely on-device with zero telemetry and no servers. The only thing that ever leaves your Mac is an optional iCloud sync of your own streak and settings.
Yes. FitLock is a native macOS app built for macOS 26 and later, on Apple Silicon. No iOS, Windows or web version — it has to own the whole screen to work.
Quick desk-friendly movements — wall sits, push-ups, planks, lunges, squats, calf raises, jumping jacks, high knees, shoulder and neck mobility, and many more — each with adjustable rep and time targets so a lockdown always fits the moment. It's a growing library, with new exercises added over time.
No. Your streak, history and settings persist locally and sync through iCloud. Quitting FitLock just pauses enforcement; relaunch and you pick up exactly where you left off.
Stop sitting.
Start moving.
