It is hard to use because it is based on the lunar calendar, which not many people know how to calculate it. We followed the prediction and chose a starting time in which we should have a boy in the next few months. Luckily the second month my wife pregnant and 10 months later, we have our boy. 5 years later, we decide to have another child, this time we wish to have a girl. We tried to follow the chart and again it gave us hard time to get it calculated right. I always want to convert the chart to an easy to use App but never had time to do it. Early this year, we got our little girl and I also started my programming. It took me another 6 months before I can finally publish it. Of course we are not 100% depend on the chart, we also tried to follow the diet and sex position which gives us better chance of what we want. BoyOrGirl is an App help parents to choose child gender.
