## What is NerveQ?

NerveQ is a personal sensation wellness self-check tool for awareness purposes only.
It is not a medical device and does not provide medical diagnosis, treatment, or advice.
Results are for personal reference — consult a healthcare professional for medical concerns.

NerveQ helps you understand your sensory wellness patterns through science-based self-checks using Heart Rate Variability (HRV) analysis, vibration perception threshold (VPT) testing, and balance assessment.

KEY FEATURES:
- PPG-based HRV measurement using your phone's rear camera and flashlight
- VPT (Vibration Perception Threshold) self-check via device haptics
- Romberg balance assessment via gyroscope
- Personalized sensory wellness score combining multiple data points
- Progress tracking to monitor your wellness over time
- Educational resources about nerve health and wellness

HOW IT WORKS:
1. Place your fingertip over the rear camera with the flashlight on for HRV measurement
2. Complete the VPT self-check using device vibration patterns
3. Perform the balance assessment guided by on-screen instructions
4. Receive a combined sensory wellness score
5. Track your results over time to identify patterns

SCIENCE-BASED APPROACH:
- VPT: Vibration perception threshold via device haptics for sensory awareness
- Romberg balance test: Gyroscope-based balance pattern measurement
- HRV analysis: RMSSD method based on published research

All measurements are processed entirely on your device. No health data is transmitted to external servers.
