Form is your AI physique coach. Scan your physique with one photo and get an honest, structured read — your physique score, body-fat estimate, and per-body-part scores — then the one change that would improve your look fastest. MOST SCANNERS STOP AT A NUMBER Form goes further than body-fat guessing. Every scan answers the question that actually matters: what should I work on next? EVERY SCAN GIVES YOU • Physique Score — overall plus leanness, muscularity, symmetry, proportion, and athleticism • Body Part Scores — chest, back, shoulders, arms, legs, core • Biggest Opportunity — the single highest-impact change for your look • Goal Readiness — how close you are to Beach Body, Visible Abs, Athletic Build, and more • A concrete plan — phase length, weekly actions, and what to expect week by week CHOOSE A GOAL, GET A PATH Lose Fat, Build Muscle, Recomp, Beach Body, Visible Abs, Athletic Build, Men's Physique, or General Fitness — your coaching re-targets to whatever you pick. YOUR PHOTOS ARE THE PROOF Compare scans side by side with a slider, track your score trend, and see what actually changed — waist leaner, V-taper improved, shoulders more defined. ASK YOUR AI PHYSIQUE COACH (PRO) Cut or bulk? Why no abs yet? What should I prioritize? Your coach answers from YOUR scans, goal, and history — not generic advice. Pro also unlocks your forecast (what your physique could realistically look like at each stage) and weekly physique reviews. PRIVATE BY DESIGN No account required. Your photos and progress stay on your device. Form's assessments are AI-generated estimates about training and conditioning, for general informational and motivational purposes only. They are not medical, health, nutritional, or fitness advice, and may be inaccurate.
