A posture corrector app you don't have to wear
You search for a posture corrector and get braces, straps and clip-on sensors. Then you picture one more thing to put on every morning before work. Meanwhile your head is drifting toward the screen again.
If you sit at a Mac most of the day, the camera above your screen can do the checking. A soft glow tells you when your posture slips, and a card shows what to fix.
Shyam Verma, 21 years on laptops. I make Poxture App, a posture corrector you don't wear, so I'm not neutral.
The short answer: At a desk all day? A camera app needs nothing to wear. Up and about most of the day? Pick a wearable sensor.
What is a posture corrector app?
A posture corrector app tells you when your posture slips, so you can fix it while it's happening. The kind on this page checks how you sit through your computer's camera, so there is nothing to put on. Others pair with a sensor you clip near your collar. This page calls those wearables.
What does a wearable posture sensor do?
A wearable posture sensor is a small device you clip or stick near your collar or upper back. Braces and straps hold you in place while you wear them. A sensor is the other kind: it tells you when you slip.
It measures the angle of the spot where it sits.1 Research on whether they change how people sit is still early.1,2
A sensor on your back knows one spot. At a desk, a lot happens above it. Your head drifts toward the screen, or a hand goes to your face. A camera above the screen can check your head, shoulders and hands while you face it.3
How does a posture corrector work without a wearable?
A Mac has a camera at the top of the screen, pointed at you. A posture correction app for Mac uses it to check how you sit, then tells you on the screen you're using.
Say your chin drops to your notes. The app names it, Looking down, shows how to raise what you're reading, and tells you once your head is back up.

Posture corrector app or wearable: which does what?
| Camera app | Wearable | |
|---|---|---|
| What you put on1,2 | Nothing | A sensor near your collar or upper back |
| What it checks1,3 | Head, shoulders and hands, while you face the camera | The angle of one spot on your back |
| Where it works | At your Mac | Wherever you wear it |
| What you need | What your Mac already has | A device you buy and wear |
| Privacy | Needs your camera, so ask where the frames go | Check what its phone app keeps |
| Best for | Long hours at a desk | Moving around, or working away from a screen |
You can also have one of each: the app for desk hours, the sensor for the rest of the day.
When is a wearable the better choice?
To be honest, an app on your Mac can't help once you walk away from your desk. Pick a wearable if:
- You stand, move between desks or work away from a screen.
- You'd rather not use a camera at all.
- You'd rather feel a buzz than see a glow.
Poxture App runs only on Apple Silicon Macs, and only checks your posture while you're at one.

Does it keep any camera pictures?
A corrector that uses your camera should tell you plainly. Poxture App reads each frame in memory and drops it. It keeps numbers, not video, like how far you lean. No camera image or video is ever sent anywhere. No pictures, ever.
You can check this yourself. The green light next to your camera comes on for a moment at each check. How to check it yourself ›

How does Poxture App help you fix your posture?
Poxture App sits in your Mac's menu bar. About once a minute, it checks how you sit using the built-in camera or an external webcam. By default, a habit like looking down or slouching has to hold for about half a minute. Then a soft glow appears at the top of your screen, with a card that shows the fix. The glow goes green once a check finds your posture fixed.
It checks eight habits, such as looking down and leaning to one side, and you can switch any of them off.
It needs an Apple Silicon Mac with macOS 15 or later. The first hour of checking each day is free for good. For your first 14 days, every feature works all day. To keep it on all day, it costs $19 once.
After 21 years hunched over laptops, I wanted a nudge at the moment it happened, so I built one.

Questions people ask
Is a posture corrector app as good as a wearable?
They're good at different things. A wearable sensor works wherever you wear it, even away from a screen, and needs no camera. An app that uses your camera works only at your computer, but you wear nothing. It also names the habit, like looking down, and shows how to fix it.1,3
Is there a posture corrector app for Mac?
Yes. Poxture App is one, and I make it, so I'm not neutral. It runs in the menu bar and checks your posture through your Mac's built-in camera or an external webcam. It needs an Apple Silicon Mac with macOS 15 or later. My list of the best posture apps for Mac covers the others.
Is a posture corrector app free?
Yes, Poxture App is. The first hour of checking each day is free for good. For your first 14 days, every feature works all day. To keep it on all day, it costs $19 once. There is no subscription.
Which habits does it check?
Eight, all on by default. Too close to the screen, looking down, hand on face, slouching, sitting still too long, hunched over, leaning to one side and not working from a proper desk setup. You can switch any of them off. Each nudge names the habit and shows how to fix it.
Does it record video of me?
No. Poxture App reads each camera frame in memory and drops it, and keeps numbers, not video. No camera image or video is ever sent anywhere. The green light next to your camera comes on for a moment at each check, so you can tell when the camera is on. The privacy page shows how to check it yourself.
