See how a low laptop screen folds your neck and upper back. Works with your phone camera, laptop camera, or webcam. It runs entirely in your browser and the camera feed never leaves your device.
Prop your phone at desk height for front checks, or turn it sideways for side-view posture scans. Same test, same URL, no app.
Open phone linkThis check reads your hunch angle from a short on-device camera scan and compares it against an evidence-based comfort range (< 15 deg). The model maps the joints involved and averages the angle so a single fidget doesn't skew your result.
Green means you're inside the healthy range. Amber means you're drifting and it's worth a small adjustment. Coral means the angle is past the comfort line for long enough to cause strain. Your number updates live, so you can watch a fix land in real time.
One test reads one signal. If you want this checked continuously — combined with posture, eye strain and fatigue, with live nudges and a progress history — that's what Pro does. It turns a one-off number into a habit that holds.
A laptop joins the screen and keyboard into one object, so one part is almost always in the wrong place for long desk sessions. If the screen is high enough, the keyboard is too high. If the keyboard is comfortable, the screen is usually too low.
Run a baseline scan in the setup you actually use, then test one change at a time. The scan gives you a posture score and a shareable card; the useful part is seeing which signals improve after the setup change.
A laptop hunch scan is ergonomic guidance, not a diagnosis. Get professional advice for persistent or worsening pain, symptoms after injury, numbness, tingling, weakness, or pain that travels into the arm.
