Chronic Trace
Know your baseline
Free · In‑App Purchases
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, and 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
1. Add yourself or anyone you track.
2. Capture a baseline when you feel well.
3. Re-check any time, and see your result against that baseline.
No extra hardware. No specialist. Just your phone.

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.

Ratings & Reviews
Start with a free trial when you create an account. Balance check-ins now include spoken guidance, so you can run them hands-free without watching the screen. The reaction, focus, and attention checks show richer results. Plus a cleaner all-white design and performance and stability improvements.
