ZBaby: Android application for pregnancy due date, fetus development simulation and weight gain during pregnancy

For awareness of becoming parents, this paper proposes the development of Z-Baby as an android application to calculate the pregnancy due date, fetus development simulation, weight gain during pregnancy and the amount of calorie in needs. Pregnancy due date is calculated based on user defined data which is the last menstruation. Next, user can view the simulation of 3D fetus development with description week by week using OpenGL ES. Then the weight gain during pregnancy is calculated from the BMI based on the specification by IOM 2009 while allowing a user to manage her weight gain as well. Updated weight data were plotted dynamically using Android Plot API. Daily calorie requirement can be calculated during pregnancy by Harris-Benedict Equation to maintain the appropriated weight for healthy baby without overeating. Other available functions are recording photos & data in monthly basis, locating mom's position on Google map to find the nearest hospital located on the map. For accuracy testing, Z-Baby has been compared to other software packages which have the same functions. Z-Baby in now available for free in Google Play.
