Not bad. 18.5% body fat — lean enough to see abs in good lighting, but not so lean you can't enjoy a burger. 42.3% muscle mass says you actually lift instead of just talking about it on your feed.
No filter

The AI that'll tell you what your trainer won't.

No compliments to sell you a membership. No "you're doing great, keep going." Just your numbers and an honest take on where you actually stand.

How it works

Three steps. Thirty seconds.

No five-screen onboarding, no masterclass required. Phone, photo, result.

Upload 1–4 photos

Fitted clothing — a tank top and shorts work best. Front and side views. From your couch, right now. Good lighting improves accuracy.

AI analyzes

Vision models read your proportions, fat distribution, and muscle mass. Calibrated against your height, weight, and age. Photos are purged from memory the second they're processed.

Get your verdict

Body fat %, muscle %, TDEE, comparison to norms, and a personal AI commentary. Numbers on your dashboard, history on your graph, truth without a filter.

"In three months I spent $12 on FatScan and dropped 13 lbs of fat. Before that, I was paying a coach $80 a month for two years and had no idea what was actually happening."

FAQ

Common questions.

Typical margin is ±5–10%, calibrated against your height, weight, and age. For medical-grade accuracy there's DEXA. For tracking progress and not lying to yourself — this is plenty.
Photos are processed entirely in memory — never written to disk or database. EXIF metadata (including GPS location) is stripped before analysis. Once you get your result, they're gone for good.
1–4 photos in fitted clothing (a tank top and shorts work great). Front and side views are the best combo. Decent lighting (natural is ideal), neutral background, straight posture. Professional quality is not required.
Yes. The Monthly and Annual plans include full scan history with per-metric graphs. Recommended frequency is one scan a week or two a month — more often than that doesn't make sense, body composition changes are slow.
FatScan is a PWA — it runs in your mobile browser and behaves like a native app. Add it to your home screen. Native iOS and Android apps are on the 2026 roadmap.
