Clearblue Cycle Calendar

Clearblue Cycle Calendar is a simple widget that allows you to keep track of your menstrual cycles. This program will only help you mark the date of your last period, and based on the average length of your cycle that you entered in the information panel, it will calculate when next period will be.

When that date comes, you can confirm that date by clicking on the corresponding box, or simply change it. The program will also tell you day by day, which day of your cycle you are in and how many days are left before your next period. However, the program will not mark the best days to conceive a child or when you shouldn't have intercourse to avoid pregnancy. The program also offers a history which shows the numbers of cycles tracked, the estimated date of your next period, the first day of your last period, and if your cycles are regular or not (28 days long). The calendar and Cycle History can be printed for you to have them at hand.

The program offers a very simple and beautiful user interface. The program itself is free, but it suggests many other commercial products this developer has to offer, so you will see advertisements at the bottom-right part of the window.

In short, if you are looking for a simple and free application to keep track of your menstrual cycles, especially if you are irregular, Clearblue Cycle Calendar may be a good choice.
