I’ve had this app for a few years and it was my number app to log my periods and now I was using it to help track the best days to get pregnant. The problem I have is the amount of ads. Every time I click anywhere, an ad pops up. I exit the ad then click on something else and then another ad pops up. The ad makes it difficult I’m in a rush to log something and every time an ad pops up. I have now been using premom as well as flo to track my periods and bbt etc as they don’t have nearly as many ads and I can quickly log what I need to and move on. I will continue to use this for my periods since I’ve had it for so long I trust the timing more but I don’t use it for anything else and I would like to. But it takes too much time. The second you open the app an add pops up.

This app I have used since back in 2012 and I FIRMLY believe this app is the reason for not one but TWO of my pregnancies and I LOVE how it incooperates the moon phases at time of conception, it also predicted the sex of my babies and was right. I am a big astrology person so I’m a believer in the moon phase stuff . Anyways if you’re trying to get pregnant, or even if you’re trying to avoid pregnancy without having to take birth control it’s nice to look at the calendar and see what days to get busy or what days to avoid either way this freaking app is AMAZING and I recommend it to literally everyone!!

Excellent health management tool

I have been using this for years to help manage a serious endocrine disorder. Any time I have to show a healthcare provider info about my cycle, body weight changes etc they are impressed with the organization and historical accurancy. The ability to show my specialist a graph of the data convinced her that I was not simply an anxious patient and helped us get to a diagnosis.

I had a problem transitioning from the free version to Pro and the developers provided excellent support. This was the one and only issue I have had in roughly 5 years of daily use.
