Not worth the price
This is a very expensive app for simply showing the most fertile and infertile days during a menstrual cycle. All you are doing is noting the day periods begin and how long between periods. This app only estimates the most fertile days. .. If it was a $1.00 app or $2.00 app it might be OK but 6.99 is a ripoff for information that you will probably cross reference on other websites/calendars as well.
