Best posture apps for Mac in 2026
By mid-afternoon your head has crept toward the screen, and you didn't feel it happen. A posture app notices for you. The apps on this list do it in one of four ways: your Mac's camera, your AirPods, a sensor you wear, or a timer. Here's which one fits how you work, with every fact about another app sourced to its maker's own website.

Checked 21 October 2026
The short answer: At a Mac all day and want nothing to wear? Start with a camera app; my pick is Poxture, which I make. AirPods in all day? Posture Pal. Nudges away from the desk too? Upright GO.

Other makers' prices are as each listed them on 21 October 2026, and they change. Poxture's is today's price.
How I picked
- I've spent 21 years hunched over laptops, and I built Poxture because I wanted something to tell me when I was doing it. For this list I looked for apps you can use at a Mac today.
- Every fact about another app comes from its maker's own site, its project page or its App Store listing, read on 21 October 2026. If I couldn't confirm a fact there, it isn't on this page. A small number after a fact points to its source in the list at the end.
- I left out apps for iPhone only, and a second break timer whose current version needs macOS 26 or later.
- The order and the picks are my view. I make Poxture, so I put it first for the situation I built it for, and I'm not neutral. Nobody paid to be on this list, and there are no affiliate links.

Poxture: for a whole day at a Mac
- Notices with
- Your Mac's camera
- Runs on
- Apple Silicon Mac, macOS 15+
- Price
- $19 once, 14 days free
- Camera images
- Never leave your Mac
Poxture checks how you sit through your Mac's built-in camera, once a minute by default. When you've been leaning in, looking down or propping your chin for three checks in a row, a soft glow at the top of the screen tells you, and a card shows how to fix it. The camera is off whenever Poxture isn't watching: when you pause, outside your work hours, during calls if you choose, and when the Mac is locked.
Choose it if
- You spend most of the day at an Apple Silicon Mac and want a nudge for leaning in, head down and a hand at your chin, with nothing to wear.
The trade-off
- It runs only on Apple Silicon Macs with macOS 15 or later, and it only sees you while you're at the Mac.

What camera apps send
A camera posture app sees you all day, so ask what it does with the pictures. Here's what each camera app on this list says, in its own words.
- Plumb: "Each image is discarded after it's measured. No photos or video are saved or uploaded."1
- SitApp: "Your webcam feed never leaves your computer."2
- Slouch Sniper: "Your camera feed is never recorded, stored, or uploaded."3
- Straighty: "All processing happens locally on your Mac. No personal data leaves your device."4
Poxture's camera images never leave your Mac: it reads each frame in memory and drops it, and keeps numbers, not video. It does send a few usage counts to PostHog's EU cloud, on by default, and you can turn them off in Settings. The privacy page lists everything it sends.
Questions
What is the best posture app for Mac?
It depends on how you work. If you sit at a Mac all day and want nothing to wear, a camera app fits; my pick is Poxture, which I make. If your AirPods are in all day, Posture Pal. If you want nudges away from the desk too, Upright GO.

Straighty is free on the Mac App Store.4 SitApp has a free plan of 1 hour a day,2 and Posture Pal is free to download.5 Stretchly is a free break timer.8 Poxture is free for 14 days, then $19 once.
Do I need to wear anything?
Not with a camera app: Poxture, Plumb, SitApp, Slouch Sniper and Straighty use the camera you already have. Posture Pal needs supported headphones in your ears,5 and Upright GO is a sensor you wear on your back.6
Do camera posture apps send video anywhere?
Each camera app on this list says its camera images stay on the computer; their own words are above. Poxture's camera images never leave your Mac, and the privacy page shows how to check the camera yourself.
Why is Poxture first?
Because I make it, and it's my pick for the situation I built it for: a whole day at a Mac. The order is my view. Nobody paid to be on this list, and there are no affiliate links.
