BMI, or body mass index, is a calculation that uses your height and weight to estimate how much body fat you have. BMI is used as a screening tool to indicate if you may be at risk for obesity, heart disease, high blood pressure, and other health problems.
A BMI calculator app calculates your BMI using your height and weight. It can also tell you if you are at risk for obesity, heart disease, high blood pressure, and other health problems.
If you are wondering how to make an app that calculates your BMI, there are several ways to do this. In this post, we’ll curate a list of resources to help you make your own BMI app.
