Femta is an application for women to keep track of their menstrual cycles. Femta calculates the probabilities of becoming pregnant for every day and displays them in charts and a calendar. You can easily record information on your menstrual cycles, pregnancy, childbirth, and lactation. Femta helps you to predict future cycles, making it possible for you to plan menstruation-free events, such as vacations or a wedding. This shareware version is a 50-day trial and costs $28.
