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.

I have been using this app for YEARS and now when I open it it starts playing Ads! This is very frustrating especially when I’m sitting in the Dr.’s office and the nurse or Dr. ask when my last period was and I can’t give that info right away I need to wait for the ad to finish playing. Also now it says I HAVE to turn my locations to ALWAYS ON to continue to use the app, why does it need to know my locations? Anyways I deleted this app and downloaded an app I used before to track pregnancy it also tracks periods so I guess this is good bye forever.

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!!
