About

Weight tracker (plus BMI)

The body mass index is a value that allows you to assess the degree of correspondence between a person’s weight and his height, and thereby indirectly judge whether the mass is insufficient, normal or overweight. It is important in determining the indications for the need for treatment. - Free - Easy to use - Measurement history - Beautiful themes Our app will help you calculate Body Mass Index based on your weight and height parameters. The original WHO formula doesn't use the age and gender of a person in the calculations. The application will help you find your normal weight, as well as control the history of measurements to achieve and maintain a normal body mass index, which is in the range of 18,5—25. The information, received in the app, is not intended for medical use and does not replace the advice of a qualified doctor. The developer is not responsible for any decisions made by you based on this information, provided as general information, and not as a substitute for the individual recommendations of a doctor.
