Why a real posture monitor beats a timer
Most "posture apps" just buzz you on a schedule. Posturion actually looks at how you're sitting right now. Using Apple's Vision framework, it tracks four axes continuously:
- Shoulder tilt — imbalance between left and right shoulders
- Forward head — how far your head has drifted toward the screen
- Head tilt — lateral neck angle
- Distance — how close you are to the display
When any axis crosses your sensitivity threshold, Posturion plays a gentle audio cue of your choice. No banner fatigue, no random pings.
Built for privacy
Webcam frames never leave your Mac. There is no cloud, no account, no analytics SDK — the camera feed is processed in real time by Apple Vision and immediately discarded.
FAQ
How does Posturion monitor my posture on Mac?
It uses the built-in webcam with Apple's Vision framework to detect body landmarks in real time, then measures shoulder tilt, forward head, head tilt, and screen distance.
Does Posturion send video or images anywhere?
No. Every frame is processed locally and discarded immediately. No cloud, no account, no analytics.
Which Macs are supported?
macOS 14 Sonoma and later, Apple Silicon or Intel. Any built-in or external webcam works.
How much CPU does it use?
Minimal. Posturion uses Apple's on-device Vision pipeline and low-rate frame sampling, so battery and CPU impact stay low on modern Macs.
