A posture app for Mac, made quieter
Leave the desk as yourself.
Sitwise is a private posture coach and sitting reminder for your Mac menu bar.
It notices when your sit drifts from the position you saved, and it keeps track of how long you have actually been in the chair. When it is time to reset or get up, Sitwise gives you a small signal—with timing you control.

The sit drifted. Sitwise asks you to sit up.
For people who work with their minds
The work gets your attention. Your body can disappear from it.
A call becomes a document. The document becomes an afternoon. You do not choose to sit for three hours; you notice three hours after they have gone.
Sitwise stays in the menu bar and gives a small part of your attention back—before the whole desk day becomes one long position.
A softer way to sit through the work you already have.
The Sitwise method
Calibrate once. Notice sooner. Move when it counts.
Posture is not a pose to hold. Sitwise learns the comfortable sit you choose for this camera, chair, and desk. After that, 100 means close to your saved sit—not a universal standard.
-
01
Save a sit you can actually keep
Settle into a comfortable working position and choose Use this sit. Recalibrate whenever the camera, chair, or desk changes.
-
02
Catch the drift
A shoulder creeps up. A chin drops. The menu-bar score helps you notice the change before it becomes the whole afternoon.
-
03
Choose the signal
Set the slouch delay and cooldown that fit your work. Sitwise stays quiet while you are standing, away, paused, or calibrating.
The other half
How you sit. And how long.
You can sit beautifully for three hours and it will still have been three hours. Sitwise keeps the clock as well as the score.
-
A posture score made for your desk
The score compares the current sit with the position you saved. It is personal to this camera, chair, and distance—not a verdict on your body.
-
A clock for actual chair time
Only time in the chair counts. Stand, step away, or pause and the sitting clock pauses too. Your reminder follows the day you actually had.
-
Small movement before a long sit
A gentle cue can remind you to shift during a static sit. After your chosen sitting interval, Sitwise asks you to stand and move for a few minutes.
-
Thirty days, kept on this Mac
See today’s sitting time, longest unbroken stretch, stands, and recent patterns. No streak to protect. No badge to lose.
Quiet by design
A reminder you can keep—not one you learn to ignore.
You choose the slouch delay, notification cooldown, sitting interval, and how long a movement break must last. Snooze when the moment is wrong. Pause when you want the camera off. Sitwise does not alert while you are standing, away, or calibrating.
On this Mac only
Your camera can notice without remembering.
Sitwise uses Apple Vision to estimate posture on your Mac. Each camera frame is processed in memory and discarded after the score. EthicsLab does not receive the image, a face print, or a pose skeleton.
- A camera frame enters memory.
- Apple Vision estimates posture on your Mac.
- The frame is discarded.

Design and development
Let the menu bar keep a small signal while the screen keeps the rest of your attention.
Calls and remote work
Take a call on your feet and let the sit clock recognise that you left the chair.
Home and office desks
Recalibrate when the camera, chair, or distance changes. Each setup gets the baseline it needs.
Built in the open
Specific claims. Visible limits.
Sitwise is built by EthicsLab Limited. We explain what the camera does, what the score means, where the numbers stay, and when the app goes quiet. If something is unclear, write to us and a person will answer.
Ask EthicsLab a questionGood to know
Questions, answered gently.
Is Sitwise a fitness app?
No. Sitwise is a Mac menu-bar posture coach and sitting reminder. There is no workout, class, calorie target, streak, or leaderboard.
What does a score of 100 mean?
It means the current sit is close to the comfortable position you saved for this camera, chair, and desk. It is not a universal measure of perfect posture, and it is not a reason to hold one shape for hours.
Does Sitwise save or upload camera footage?
No. Camera frames are processed in memory on your Mac with Apple Vision and discarded after each score. Sitwise does not write frames to disk or send them to EthicsLab.
Will it nag me?
You choose the delay, cooldown, sitting interval, break duration, and sleep hours. Sitwise stays quiet when you are standing, away, paused, or calibrating. You can snooze or pause whenever you need to.
Does it know when I stand or step away?
Yes. Standing and away are different from slouching. The sitting clock pauses when you leave the chair, and a movement break counts after the duration you set.
Do I need special equipment?
You need a Mac running macOS 14 or later and a camera. The default Mac webcam is enough. Recalibrate if the camera, chair, desk, or distance changes.
Does it work with a standing desk?
Yes. Sitwise recognises a short stand as movement. If you remain standing with the camera still at sitting height, it may ask you to raise the camera and recalibrate.
Is Sitwise a medical device?
No. Sitwise is a general desk-awareness tool. It does not diagnose, treat, or prevent a medical condition.
When does Sitwise launch?
Soon, on the Mac App Store. Join the launch list and we will send one email when it is available.
