“Amazing, I love this app, works great.”

“Got pregnant first time around with this app.”

“Really good information, clear and simple layout, easy to use.”

My Ovulation Calculator is a simple and easy to use application to calculate the time of ovulation and determine the fertile period. By just recording the first date of your last menstrual period and the average number of days in your menstrual cycle, your ovulation date and your fertile period will be shown. Being intimate during the fertile period greatly improves the chances for you to conceive. The app also shows the expected date of delivery if you happen to conceive at that time.

This app is designed for iPhones, iPads and iPods Touch.
