Determining body mass index (BMI) on an iPhone involves using an application or online tool to calculate a numerical value based on height and weight measurements. This value provides an indication of overall weight status, categorizing individuals as underweight, normal weight, overweight, or obese.
BMI calculation is particularly relevant for individuals seeking to monitor their weight and overall health, as it serves as a screening tool for potential weight-related health risks. Additionally, the widespread adoption of smartphones has made BMI calculation more accessible and convenient than ever before. Historically, BMI was calculated manually using a formula, but the advent of mobile technology has streamlined the process significantly.
