8 weeks into a cut or bulk and still not sure it's working? Bodilab reads your body fat, lean mass and real change from one photo — plus the one move to make next.
Trained for weeks and still not sure it's working? The scale hides it. The mirror lies to you daily. Bodilab reads a single photo and shows what actually changed.
From one photo, AI reads a full body-composition profile: body fat %, lean mass, 12 muscle groups, FFMI, symmetry, V-taper and an overall score — then tells you the one thing to do next. It's the answer-check on your effort — the depth of a lab, from a photo.
Who it's for (all genders)
• You track but can't tell if fat or muscle is moving
• You take progress photos but lose them in your camera roll
• You want to lose fat while keeping muscle (recomp)
• Cutting, bulking, post-partum — you're serious about your body
What you get
• Progress-photo timeline & before/after compare
• Body-fat % estimate — at home, every week (between InBody/DEXA visits)
• Muscle (lean mass) & per-part change
• Calibrate the estimate to your own InBody/DEXA reading
• Where you are now, and what to do next to reach your goal
• An AI coach that answers "what changed?" from your own numbers
Not more numbers — the ability to keep going. Because when you can see it, you stay consistent.
Body composition is an AI estimate, not medical advice. For health decisions, consult a professional.
