There is an Event Calendar, Menstruation Calendar, and Complete National Calendar.
The Friends of Mother application has several features that mean that mothers don't have to worry about: estimated menstrual dates, calculating the fertile period, determining ideal weight, calculating expenses, remembering appointment dates or event schedules, important notes, and looking for a wall calendar that is complete with red dates and mass leave.
Suitable for use by anyone, including those who are promil or pregnant friends.
