Not for "irregular" periods

It seemed really good and organized at first but then I realized it cannot account for periods that last longer than 5 days. When I tried to mark the 10th day of my period it said it was “too close to my previous period” but it was actually part of the same cycle. It also counts the spotting at the begining when my doc clearly stated that the first day of the cycle was the first day of real flow, not spotting the few days before. After I realized it was tracking right, I knew all the fertile days were most likely off too.

Nice simple application, but suffers from a few small issues

Program works as advertised, but suffers from a serious of small issues that should be fixed. For example, if you accidentally enter data on the wrong day, it is impossible to remove that data. There is no way to print the calendar besides taking a screenshot. The temperatue graphs are broken over calendar months which makes it hard to see the complete cycles. Sometimes the coloring of the "period days" is broken (I reported this issue to the developer who promptly confirmed the problem, but then never fixed it.). Etc.

Would upgrade review to five stars if these issues were fixed.

TTC #1 Great for Remembering Cycle Dates

This app takes the guess work out of trying to figure out how long your average cycle length is. It also gives you places for notes, basal body temp, and symptoms like cervical mucus, pms, stress, SEX, etc. It really is work the money if you are seriously trying to get pregnant. I would suggest buying this app as soon as you get off birth control. My Doctor was surprised at how well it helps keep track of all my information. (Plus this way, I don't have to remember everything). The only thing is that if you forget your password, there isn't a security question…and you are locked out.
