What the scan does
Five dimensions.
One honest score.
Single photo
One photo. Full breakdown
Pose, snap, score. Zenith reads composition, muscle development, symmetry, definition, and proportion from a single image.
Tier-coded scores
S, A, B, C — at a glance
Every dimension lands in a tier with its own colour. You can see your strongest area and your weakest the moment the scan completes.
Tracked over time
Comparable week-to-week
Every scan is saved. Watch your overall score and individual dimensions trend across weeks of training — real visual change, captured.
Shareable summary
A card built to share
Each scan generates a clean summary card — perfect for stories, group chats, or your own private log.
Private by default
Your photos, your account
Photos are stored against your account and used only to produce the rating. Never sold. Never shared. See the Privacy Policy.
Lighting tips built in
Repeatable, on purpose
Consistent pose, lighting, and angle make scans comparable. Zenith guides you through it the first time and reminds you on every subsequent scan.
Why physique rating
Scales lie. Mirrors flatter.
The scan doesn't.
Weight changes are noisy. Mirror checks are biased. Calipers are fiddly. Most progress signals in fitness are either too coarse to react to or too subjective to trust.
Zenith's physique rating gives you a third reading. A repeatable, AI-evaluated score that captures composition, development, and proportion in one number — and lets you watch that number trend across weeks of consistent training.
It's not a replacement for the scale or for the mirror. It's a third axis. Use all three.
