BMI is a screening measure, not a diagnosis; body composition and individual health require professional context.
Frequently asked questions
What is a healthy BMI range?
For most adults, the standard normal category is 18.5 through 24.9.
Can children use this category result?
No. Children and teenagers require age- and sex-specific percentile charts.
Does BMI measure body fat directly?
No. It is a weight-to-height screening ratio and cannot distinguish muscle from fat.
Is my health data stored?
No. Values are calculated locally and are not saved or transmitted.
