I know it will get better....
Is true that it might not work with women with irregular cycles (like me) but I still went ahead and got it hoping that with an update it will improve. It needs to store a history and the ability to store events, specially when woman use the temperature, stick or saliva microscope to check for fertile days. I record those in the iPod calendar. So far is accurate with the fertility days given by the ovulation calendar, when checked with the other methods I use.
