Quick answers.

How is BMI calculated?

The formula is weight divided by the square of height. In metric, it is kilograms divided by metres squared (kg/m²).

What are the standard BMI categories?

Underweight is below 18.5, healthy weight is 18.5 to 24.9, overweight is 25 to 29.9, and obese is 30 or higher.

Is BMI an accurate measure of health?

BMI is a useful screening tool but does not account for muscle mass, bone density, or body composition. Athletes may have a high BMI due to muscle rather than body fat.

Is my physical data stored?

No. All calculations are performed on your device and your height or weight data is never sent to a server.
