## What is BellyMetric?

Measure more than BMI.

BellyMetric calculates BMI, ABSI, BRI, and waist-to-height ratio from height, weight, and waist circumference, giving you a clearer view of body shape metrics in seconds.

WHY USE BELLYMETRIC

- Calculate four body-shape metrics in one place
- Add waist circumference for context that BMI alone can miss
- See plain-language explanations for each result
- Review scientific references behind BMI, ABSI, BRI, and WHtR
- Use the app in 11 languages with automatic language detection
- Keep the experience simple: enter values, get results, learn what they mean

INCLUDED METRICS

BMI - Body Mass Index, a common height-and-weight screening measure.

ABSI - A Body Shape Index, using waist circumference with height and BMI.

BRI - Body Roundness Index, using height and waist circumference to estimate body shape.

WHtR - Waist-to-Height Ratio, a simple waist-based indicator often used for central obesity screening.

BUILT FOR QUICK CHECKS
