Excellent but disappointed

I do like interface, colors and others except only 1 thing. One of the reasons I bought this app is that it supports Lunar calendars for anniversaries but I cant know how to set this in the app. Therefore I email to them twice but there is no response from them...... Except this its the excellent app to me.
