Chart your cycle, one day at a time.

+

Log the first day of your last period and your typical cycle length — the calendar plots your period, fertile window, and ovulation day automatically, and updates every time you adjust the numbers.

Six days a cycle actually matter.

+

Conception is only possible in the days leading up to and including ovulation. This view uses the same cycle dates to surface your fertile window, plus what basal body temperature and cervical mucus typically do each day around it.

Every week of pregnancy, mapped.

+

Enter the first day of your last menstrual period (LMP) — pregnancy is dated from there, not from conception. The tracker converts today's date into a gestational week and your estimated due date.

+
+

Prefilled with an example LMP — enter your own for your real week and due date.
