Baby Tracker can help you if you know you're pregnant, but want to know when exactly your baby should make his big entrance. Our due date calculator can help determine when your baby may be born, based on the date of your last menstrual period and the length of your cycle. Please remember that your baby will come when it is ready, so this result is an estimate only. This app will also calculate exactly how many days until your due date and will update every time you open the app. Your baby gets bigger and stronger every week. Baby Tracker app helps you track his weight, height, head circumference, heart beat and BMI before the baby is born and after--it's like a medical history of visits and revisions. You can also track baby growth and development for more than one baby.
