Check visible wrist, elbow, shoulder and head position while typing. 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 typing risk 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.
Long typing sessions can pull wrists up, shoulders forward, and the head toward the screen.
Place your camera so shoulders, elbows, and wrists are visible. Run the check while typing naturally, not while posing.
A member session can watch posture while you actually work and nudge changes when the pattern returns.
It looks at visible wrist height, elbow height, shoulder level, and a simple head-position proxy while you type.
The tool compares wrists and elbows. If your hands are outside the camera frame, the typing-specific signal is weaker.
Bring the keyboard and mouse closer, keep wrists closer to elbow height, and relax both shoulders before continuing.
