Is this a free AI body fat scanner?
You can use it as a free photo-based body fat estimator. It is not a medical scan: AI reviews visible features in your photo and returns an uncertain range. It cannot see inside your body or directly measure body fat.
Can AI calculate my body fat percentage from a photo?
It can estimate a broad range from visible features. It cannot directly measure body fat, determine your health or provide a validated error margin. Lighting, clothing and pose can change the result. Read about AI body fat estimate accuracy.
Is this AI body fat calculator free?
Your photo estimate, physique score and full breakdown are free. The personalized 90-day workout plan is an optional US$9.99 purchase. See exactly what’s free and what’s paid.
How can I check my body fat without a photo?
Use the separate height-and-waist body fat calculator. It uses the published Relative Fat Mass equation and labels its result separately from the AI photo estimate.
What does my body fat estimate mean?
It is an uncertain estimate of the proportion of body weight that is fat. It is a starting point for your own check-ins, not a diagnosis or a target you have to reach. See how the estimates and scores work. You can also read the body fat percentage chart guide for reference ranges and their limits.
