Weight Chart helps to monitor your weight and waist circumference over time. Newer studies show that a waist to height ratio of over 0.5 increases the risk of cardiovascular diseases, a ratio over 0.6 significantly. It's a better measure than the well known body mass index (BMI) because it takes the distribution of fat into account more accurately. *** The free version is restricted to store the last 3 entries only *** More Features: - chart weight, BMI and waist circumference to height ratio - enter and edit data for any date - E-Mail the data for backup - turn the phone to switch between chart and data entry - switch between metric and imperial units - support for the iPhone 6 and 6+
