What is Periodic Calendar?
Periodic Calendar is an application which assists in women menstrual cycles tracking and fertility periods prediction. This information can be used either to become pregnant or to prevent pregnancy.
At this point the fertility prediction is based on the calendar method which is not very precise. It is not recommended to use this method alone for the birth control.
In the future versions it is planned to add support for the BBT (Basal Body Temperature) method which in addition to the calendar method provides more precise predictions. However, this method requires more efforts (daily temperature measurements) while the calendar method requires only to remember the cycle start dates and enter them somehow into the program. The effectiveness of the BBT method itself is about 80-90%. Combining more than one method makes the predictions more effective.
Other self-observations methods I know are really hard to support on a computer.
