Polymarket

Polymarket is an all-in-one utility app with a BMI calculator that gives you more than just a number, it provides a labeled category, a visual scale indicator, and a history log so you can track your body mass index over time. Enter your height and weight in either metric (cm and kg) or imperial (feet, inches, and pounds), Polymarket handles the formula and returns your precise BMI value instantly. The category label tells you where your result falls: Underweight, Normal, Overweight, or Obese, displayed alongside the number so the clinical significance is immediately clear. The visual scale indicator places your BMI value on a graphical representation of the standard BMI range, so you can see at a glance not just which category you're in but how close you are to the boundary of the next one. The history log saves all your BMI measurements with dates, and Polymarket works entirely offline with no account required, the BMI calculator and all nine other tools are available from the first launch.
