■ Main Features
Instant FFMI & Normalized FFMI Calculation
Simply enter your height, weight, and body fat percentage to instantly calculate your Fat-Free Mass Index (FFMI) and "Normalized FFMI," which adjusts for height differences to ensure a fair evaluation.
[NEW] Target FFMI Reverse Simulator
"What changes do I need to make to reach a Normalized FFMI of 22?"
Just set your target value, and the app automatically generates a "Body Fat % and Target Weight combination list" based on your height. It strongly supports your specific goal setting, from bulking up to cutting, by factoring in body fat fluctuations.
Classification Rank Display
Based on your calculated values, it provides intuitive feedback on where your muscle mass ranks, from below average up to the "God-like" level.
Global Support
Full compatibility with both Metric (cm/kg) and Imperial (ft/lbs) systems. It also supports multiple languages (Japanese, English, Korean, Traditional Chinese, and German).
