Introducing CHi – Comprehensive Health Index Your go-to app, AiBMI, has evolved. We've integrated the revolutionary CHi system to give you an intelligence report that goes far beyond the scale and basic BMI calculation. CHi is a single, powerful, data-driven score that distills complex anthropometric and body composition data into an easy-to-understand health index. It’s the ultimate measure of where your body really stands. Take the first step toward a healthier you today! Plus, get personalized suggestions for a healthier lifestyle, along with trusted healthcare resources and citations. CHi: The Science Behind Your Score. Why trust CHi over BMI? Because CHi uses your unique body measurements (Waist, Hip, Neck, Height, and Weight) to analyze the three critical pillars of your health, delivering targeted advice you can act on: Visceral Fat Risk (WHR): Assesses the dangerous fat around your organs. Low WHR might be a vanity goal, but CHi alerts you when it's medically concerning. Body Fat Percentage (BFP): Pinpoints the true ratio of fat to lean mass—essential for optimizing diet. Muscle Mass Potential (MMP): Measures strength and identifies the risk of age-related muscle loss. Disclaimer & Safety: AiBMI strictly provides general wellness and fitness information. The data and advice provided by AiBMI with CHi are for informational purposes only. They are not a substitute for professional medical advice, diagnosis, or treatment. Do not use this app to diagnose or manage any disease or medical condition.

Verdict
The clearest difference is in-app purchases: AiBMI at none against Lean Mass Calculator's 4. AiBMI also leads on ads (none vs shown) and update cadence (monthly vs every 6 months). Lean Mass Calculator's advantage is iOS requirement (15.0 vs 17.2). On price and device support there is nothing between them.
