This easy-to-use program charts the best times to conceive a boy or girl, but the constant nag screen reminder is a turnoff. Sundo Ovulation Calendar's straightforward interface easily captures luteal phase and menstrual date and cycle information.
The color-coded calendar marks projected menstruation dates as red, while days with the highest probability of conceiving a baby boy or girl are highlighted in blue and yellow respectively. It's simple but easy to read. Unlike similar applications, Sundo Ovulation Calendar doesn't record actual menstruation dates or create any charts or reports. You can view projections by month up to the year 2099 and the scroll bars make it easy to view specific months in a specific year. There's no help file, but one isn't really necessary.
Although you're warned in advance about the pop-ups, it doesn't make them any less annoying because they do, as promised, appear every single time you select a date or enter information. Aside from this demo quirk, the program works quickly and couldn't be simpler to use.
