Women's Health Diary is a mobile health app designed to help women monitor their health with ease. The app offers a comprehensive suite of applications, including the Weight, Body Mass Index (BMI) and Calculator and Tracker App, Menstrual Diary App, Health Screening App, Health Appointment App, and Immunization App.

With the Weight, BMI and Calculator and Tracker App, users can record their weight, height, and calculate their BMI using Imperial or Metric measurements. The app also shows whether the user is underweight, of normal weight, overweight, obese, or grossly obese. If the BMI is abnormal, the app suggests the weight the user needs to gain or lose to have a normal BMI. Users can keep the history of their weight and BMI in the app and set alerts to remind them to weigh themselves.

The Menstrual Diary App allows users to record their periods in the calendar, highlighting the next period based on the average interval of the last three periods. The app also displays the date of ovulation and the fertile period for the month, and keeps track of the previous periods, durations, and intervals in the History Window. Users can set alerts to remind them of the fertile period and three days before their next possible period.
