Notice visible jaw and mouth-center drift during focused desk work. 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 jaw signal from a short on-device camera scan and compares it against an evidence-based comfort range (< 20%). 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.
Focused screen work can pair with jaw tension, leaning, or a tilted head position. A short landmark check can make that pattern easier to notice.
Use a shifted result as a cue to relax your jaw, sit back, and check whether your screen or keyboard placement is pulling you forward.
It compares mouth center, nose, eye midpoint, and a simple jaw-open landmark signal.
No. It is a desk-work posture cue based on visible camera landmarks.
Relax your jaw, close your mouth gently, sit back, and re-run the check after adjusting your screen posture.
