Read blink, yawn and head-drop signals after long video calls. 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 fatigue index from a short on-device camera scan and compares it against an evidence-based comfort range (< 25). 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.
Video calls can create long periods of fixed gaze, low blink behavior, and limited movement. This check gives a quick signal before you jump into the next task.
Members can use live sessions to combine meeting fatigue signals with posture drift, eye-break timing, and reset reminders during real work blocks.
