We track our steps, our sleep, and our heart rate. How sharp we feel day to day has had nothing. Chronic Trace changes that. Chronic Trace turns the camera already in your pocket into a personal wellness check for how you are performing day to day. In a single capture it reads involuntary signals that are hard to fake on purpose: eye movement, balance, focus, and reaction. It combines them into one simple index, scored against your own baseline rather than a population average. That is what makes subtle change over time visible. WHAT IT MEASURES Eyes: how steadily your eyes track and shift Balance: body sway, captured by the camera Focus: attention and processing speed Reaction: response speed HOW IT WORKS Add yourself or anyone you track. Capture a baseline when you feel well. Re-check any time, and see your result against that baseline. No extra hardware. No specialist. Just your phone.
