Body Fat Calculator (PRO)
Body Fat Composition Tracker
Free · In‑App Purchases
Body fat calculator with 9 research-backed formulas, measurement history, and Apple Health sync. Cross-check methods and know your real numbers.
Your weight doesn't tell the whole story. Body fat percentage is what actually matters for health, fitness, and performance — and most apps only give you one rough estimate.
Body Fat Calculator gives you 9 different research-backed formulas so you can cross-reference results and get the most accurate picture of your body composition.
THREE FREE METHODS
- YMCA — quick estimate using weight and waist
- Modified YMCA — improved accuracy with additional measurements
- U.S. Navy — the same formula used by the military to assess fitness
SIX PRO+ METHODS
- Jackson & Pollock 3-Site, 4-Site, and 7-Site — the industry standard for skinfold testing
- Durnin & Womersley — clinical gold standard used in exercise science research
- Covert Bailey — comprehensive method using multiple circumference sites
- Parrillo 9-Site — the most detailed method, designed for bodybuilders and athletes
Every formula is implemented directly from peer-reviewed research with documented accuracy ranges (±3–7% depending on method and technique).
