One Number. Your Entire Health.
WVI — Wellness Vitality Index — is a single score from 0 to 100 that tells you exactly how well your body is performing today. It’s calculated from 8 sensors on your Wellex band, updated every morning.
How WVI Is Calculated
Your WVI combines data from all 8 biometric channels: ECG rhythm stability, heart rate variability (HRV), blood oxygen levels (SpO2), sleep architecture (deep/light/REM ratios), stress patterns, daily activity, and skin temperature trends.
The AI weighs each factor based on medical research and your personal baseline. No two people have the same WVI calculation — it’s personalized to your body.
Why WVI Matters for Yield
Higher WVI = higher yield tier. At WVI 70, you’re earning up to 12% monthly on your deposits. At WVI 90+, up to 20%. The system rewards you for taking care of yourself. Your morning jog literally increases your income.
How to Improve Your WVI
- Sleep: 7-9 hours, consistent timing. This alone can boost WVI by 10-15 points.
- Activity: 30 min daily movement. Doesn’t need to be intense.
- Stress: The AI coach helps with breathing exercises and rest recommendations.
- Consistency: WVI rewards streaks. 7 days of good habits > 1 perfect day.
