Your scale is lying to you. Smart scales measure electrical impedance, which changes based on hydration, time of day, and what you ate. That's not body fat data — that's noise. Body Fat Scanner uses AI vision to estimate your body fat percentage from photos. No electrodes. No hydration games. Just a straightforward estimate based on what your body actually looks like. HOW IT WORKS Take a photo or upload from your camera roll Enter basic measurements (age, height, weight) Get your AI-powered body fat estimate in seconds Track progress over time with visual photo history Toggle Roast My Physique mode for brutally honest AI feedback WHY PHOTOS BEAT SCALES Even DEXA scans — the supposed gold standard — have meaningful individual variance. Your bathroom scale has no idea what's happening to your body composition. Photos capture what actually changes: how you look. This app tracks that. FEATURES AI body fat estimation from photos Progress tracking with visual history Roast My Physique mode: choose clinical or roast-style feedback Private and secure — your photos, your data 3 free scans to try it SUBSCRIPTION Try it free with 3 scans.

About

ProportionIQ

ProportionIQ turns a few photos into a clear, personalized read on your physique — measured, not guessed. Take your scan and get: • ProportionIQ Score — one headline score, free on every scan. • Body composition — an estimated body-fat range, FFMI, and lean mass. • Muscle Map — all 12 muscle groups scored, with a development band and a coach's note on each. • Golden-Ratio & Proportion analysis — your V-Taper and Symmetry scores, and how close every ratio sits to the classical ideal, personalized to your frame. • Ideal Targets & Gap-to-Ideal — where you are versus your frame's ideal, and the highest-leverage area to work on next. • AI Coach — chat that actually knows your numbers, gaps, and plan (Pro). • Progress — trends for your score, body fat, FFMI, and proportion over time, with side-by-side comparison. Built to be honest and private: • Your photos are analyzed and then discarded on our servers — your photo history is kept only on your device, encrypted. You can blur faces before analysis, and delete any photo or your whole account anytime. • Body-neutral by design. ProportionIQ scores your OWN physique against aesthetic-proportion and health references. It never rates, ranks, or votes on other people, and it uses supportive, non-judgmental language throughout. • Estimates, honestly labeled. Outputs are AI estimates for informational and motivational use — not medical advice, and not a substitute for a professional. Membership (ProportionIQ Pro): • Unlocks the full report: the complete Muscle Map, exact body composition, Ideal Targets, the Weak-Point plan, trends, comparison, the AI Coach, and your private photo vault. • Monthly or annual plans; the annual plan includes a 7-day free trial. Manage or cancel anytime in your Apple ID settings. ProportionIQ is for adults 18+.
