Trust

Photos of your body deserve care.

Privacy and honesty aren't features we bolted on; they shape how the product works.

Your photos, handled with care

One purpose: creating your results. Your photos are shared only with the providers needed to create or store them. Guest scans auto-delete; sign in and you can delete your saved photos and results anytime.

Honest by design

Ranges over false precision. No body-shaming mechanics, ever. Results describe, they don't judge. And nothing about your body is used to pressure you.

Scan free every week

Free includes an estimated body-fat range, confidence, summary, visible scores, photo-quality guidance, and a limited muscle and focus view. Pro unlocks deeper detail, trends, strategy, and comparisons.

Pricing

Simple, and honest too.

FAQ

Fair questions.

It looks for visible physique signals such as body fat appearance, muscle definition, proportions, symmetry, and balance. These signals are useful for fitness check-ins, not diagnosis.

No. A photo can support a directional body fat range, but it cannot provide clinical precision. Lighting, pose, camera distance, clothing, and recovery state can all change the result.

Ranges are more honest for photo-based inputs. They help users track direction without overreacting to a fake-precise single number.

Front, side, and back photos give more context for fat distribution, muscle balance, and symmetry than one angle alone.

It cannot know exact tissue composition, diagnose health conditions, or replace methods such as DEXA, BodPod, or professional assessment.

Use similar lighting, camera height, distance, clothing, timing, and relaxed pose each time. Repeatability matters more than making one photo look perfect.
