Why SitSense Works
Real data. Real people. Real posture change.
How SitSense Works
SitSense uses your webcam to track posture in real time, score your alignment, and guide you back to neutral form before tension builds. Every session includes live posture scoring, streaks, micro-goals, and personalized nudges based on head–neck angle, forward head posture, and tilt. Leaderboards, badges, and daily goals turn healthy posture into a habit that sticks.
Who SitSense Is For
SitSense helps anyone who spends long hours at a desk: remote workers, students, software engineers, designers, call center teams, and even gamers. If your day involves meetings, deep focus sessions, or long study blocks, SitSense keeps your posture consistent, reduces neck and shoulder tension, and builds healthier work habits automatically in the background.
Why Webcam Tracking Works
Webcam-based tracking works because it gives you feedback exactly when posture starts to drift. Our analysis of 540+ hours of real posture data shows most strain begins with subtle alignment changes—head–neck angle, forward head posture, and tilt. SitSense detects these moments early and guides you to reset before discomfort and fatigue build up.
Private. Local. Secure.

How does SitSense protect my privacy?
SitSense processes all video analysis locally on your device—no video or images are ever stored or transmitted. Only numerical posture metrics are saved to help track your progress over time. The interface is minimal and can be hidden, and all video processing happens in your browser without external network calls.
What devices and browsers are supported?
SitSense works on any device with a webcam and modern browser. We support Chrome, Firefox, Safari, and Edge on Windows, macOS, and Linux. The app works entirely in your browser—no downloads or installations required.
How does SitSense compare to wearable posture trackers?
Unlike wearables like Upright GO or the discontinued Lumo Lift, SitSense uses your webcam to analyze full upper-body posture—no device to wear, charge, or clip on. Webcam-based tracking detects forward head posture and slouching more accurately than single-point sensors.
