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. SUBSCRIPTION Chronic Trace requires a paid subscription to run check-ins and view results. Plans are $14.99 per month or $149.99 per year. Payment is charged to your Apple Account at confirmation of purchase. Your subscription renews automatically unless it is canceled at least 24 hours before the end of the current period. You can manage or cancel anytime in your Apple Account settings. BUILT FOR Athletes, veterans, families, and anyone who wants to keep an eye on how they are doing over time. PRIVATE BY DESIGN Sessions can be tracked fully anonymized. Your data is yours. IMPORTANT Chronic Trace is a wellness self-tracking tool, not a medical device. It does not diagnose, treat, cure, or prevent any condition, and its output reflects change versus your own baseline, not a diagnosis. Always seek the advice of a physician or other qualified health provider before making any medical decision or with any questions you may have about a medical condition. Never disregard professional medical advice or delay seeking it because of something you measured in this app. Privacy Policy: https://www.chronictraceapp.com/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
