Very detailed but incredibly accurate

I downloaded this and another app to see which I liked better. While this one definitely was overwhelming at first with all of the info given and also asked for, it customized the calendar to MY body! The other app just gave approximate dates for the "average" cycle not taking into account the info I gave. Most women do not fall into the "average" category. I find that it is almost dead on, even with my ovulation dates, which are much later than other apps consider "normal". While harder to get the hang of, it is definitely the best app out there.
