"Growth Chart Pro" helps to keep track of your children’s growth from birth to 20 years old. The app accurately calculates the growth percentile of the weight, height and head circumference based on age and gender, using the most recent US CDC and WHO data, the same data that are commonly used by pediatricians.You can add multiple children and save all your data to the database for future review. The saved data can be viewed as tables, or as graphs (values/percentiles vs. ages). It provides you with the median value of weight/height/head CC at your children’s age, and you can get the values at any percentile by easily sliding the percentage bar. So you can compare your children’s growth with that of others, and log your children’s growth history and learn the trend.Key features include:-Keep track the growth of one or multiple children;-Save data to SD card or restore the saved data later;-Provide growth data for infant, toddler, teenager and youth below 20 years old;-Support multiple units for measures, including lb/oz/ft/in and cm/kg;-Log and view the growth history;-Analyze data using tables or graph.
