Spina vs Poxture App
You drift forward, twenty seconds pass, and a small window with you and a posture outline appears above your work. That is Spina, a $7.99 Mac app in early access. Poxture App checks for eight habits through your Mac's camera, and a soft glow and a card tell you which one to fix. Every fact about Spina below comes from Spina's own website.

What Spina is
Spina is a Mac menu-bar app for macOS 12 or later. Its site says "spina notices you've drifted from your own upright posture." Setup has three steps: you sit the way you'd like to sit, then show how you slouch by the end of the day, then turn your head left and right "as if glancing at a second monitor". The site footer says "v0.1 · early access", and that other platforms "will come later, but not this year."1
The site names no company or person. Its contact is a Telegram handle, and its terms are under the laws of the Republic of Kazakhstan.2,4
The mirror, and the glow
When you drift, Spina first changes your score and its menu-bar icon. Twenty seconds in, the mirror appears: "a small window with you and a posture outline appears nearby", above everything you have open. It closes when you sit up, with "nothing to dismiss, no follow-up reminders." Every notification has a "not actually slouching" button.1
Poxture App never saves or shows a camera picture. When you've been looking down or slouching for about half a minute, by default, a soft glow at the top of the screen tells you, and a card shows how to fix it. When you have, the glow turns green. If it got you wrong, click Wrong nudge? on the card and Poxture App adjusts.
Price
On 2 November 2026 Spina cost $7.99, paid once: "buy once. then forget about it." You can ask for your money back within 14 days of purchase. Checkout goes through Polar.sh.1,2,3
Poxture App costs more. Poxture App is free to use: the first hour of each day is free for good, and for your first 14 days every feature works all day. To keep it on all day you pay $19 once, for one Mac, with every 1.x update and a full refund within 14 days, no questions.
Privacy
Spina's privacy policy says "Camera frames are evaluated and discarded", and that they are "never written to disk and never sent to any server." It also says "No telemetry. No crash reports unless you opt in." On what leaves your Mac, the policy says two things: that nothing leaves your computer except checks for a newer version, and that license activation is its one outbound request.1,2
Poxture App's camera images never leave your Mac either. It reads each frame in memory and drops it. It sends more than Spina says it does. Poxture App sends usage counts with a random install number and, once a day, rounded posture scores with no install number, and supporters can turn both off in Settings. The privacy page lists every item.
What Poxture App checks
Spina names one habit: drifting from your upright posture, with your head forward and shoulders rounded.1
Poxture App checks for eight habits: 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. It runs on Apple Silicon Macs with macOS 15 or later.
