BodyMassIndex-Tool app for iPhone and iPad

The body mass index (BMI) is an important measure of your health and can help determine if you are overweight or underweight. If your BMI is high, you may have an increased risk of high blood pressure, heart disease, type 2 diabetes, and other serious health problems.
The body mass index calculator above can help you determine your BMI. This is just your weight, with a high degree of measurement.

BMI below 18.5 indicates you are underweight. 18.5 to 24.9 BMI shows that you are within a healthy weight range. BMI above 25 indicates you are overweight.
