Free tools
All free, no sign-up, instant. Every number a calculator produces comes with a "so what" attached — a visual reference, percentile data, or a first-impression read.
Height comparison
Two heights side by side at true scale: the gap in cm and inches, and where the eye lines land. Embeddable on your own site.
FFMI calculator
Fat-Free Mass Index + normalized FFMI with natural-lifter context — every score from 16-28 has its own breakdown page.
Body fat calculator (Navy method)
Estimate body fat from height, neck, and waist — then jump straight to the visual reference for your exact percent.
Facial proportions test
Measure canthal tilt, facial thirds, and midface ratio in your browser — the photo never leaves your device.
Reference data
Tools measure one input — the test reads the combination
1 minute. The AI combines face × physique × outfit × vibe and writes what the 1.2-second first impression actually registers — plus your ceiling.
