FAQ

What can LeanLens analyze from photos?

LeanLens can estimate a body fat range, show muscle balance and symmetry context, surface focus areas, and help you compare saved check-ins over time.

Which LeanLens feature should I start with?

Start with the AI Body Analyzer for the broadest read, the AI Body Fat Analyzer for body fat signal, or the Body Transformation Tracker if you care most about weekly progress.

Does LeanLens give an exact body fat percentage?

No. LeanLens uses confidence-aware ranges because photos have lighting, pose, angle, and recovery noise. Ranges are more honest than fake-precise single numbers.

Can I track progress over time?

Yes. Body Transformation Tracker and saved snapshots help you compare consistent check-ins, review trends, and avoid overreacting to one noisy photo.

How does LeanLens handle uploaded photos?

Photos are processed to generate your result and are not stored in the LeanLens database after processing. Saved snapshots are optional when you want progress tracking.
