This is a free BMI calculator for the iphone and ipod touch. BMI stands for "Body Mass Index," which is a health tool commonly used to measure your weight relative to your height. By keeping your BMI in check - working out, eating right, etc. - you can avoid health issues such as diabetes, high blood pressure and heart disease.

It's very easy to calculate this yourself and stay healthy using our simple app. Every time you weigh yourself, plug in your numbers and see if your BMI has gone up or down. If it's gone down, congrats! If it's gone up... well, it might be time to hit the gym.
