Customer Reviews

Long time user

I've been using this free app for years and am extremely happy with the most recent upgrades/updates! As of a year and a half ago, the free version was VERY limited with fertility tracking and other features, so I downloaded an alternative to use to help me get pregnant. Now that my cycle has returned post partum, I went to enter things and was surprised/excited to see all the upgrades! I will be deleting my alternative app and continue to use this one when we try for our 2nd baby! My only wish is that the fertility tracking charts be a little more integrated (utilizing more than one factor per graph to be able to see the changes month to month all in one place). Other than that, it's awesome! Great selection of emotions, place to enter BBT and OPK/pregnancy test results, able to enter other fertility markers such as cervical openness, height, firmness, and discharge. Much much improved from previous years!!

Love it

I have been using this app for over 3 1/2 years and I have never had any complaints. I love how easy it is to keep track of my periods and all sorts of other details about my body such as when I tend to get cramps, how heavy my flow is on each day, what times of the month I get acne, my mood, my weight, and so many other things. I also love the forum. I have had so many questions answered by so many lovely and understand ladies. I would recommend this app to anyone. The only feature I wish this app had is a birth control reminder setting to remind me to take my pilI but also so I can see the symptoms that I get in regards to my birth control throughout the month.


I think this app is awesome. I especially love it since the update. I like how I can add my moods and even can monitor changes in my weight, body temperature, and various other symptoms with each cycle. I also like how it reminds me to do a monthly breast exam. Also, I like how it lets me know of the beginning of the week leading up to ovulation. This app is very helpful since I have so many things going on and do not have to remember exactly when or what happened during my LMP. The only fluke is that it took the app a little over a year to see my cycle occurred every 27 days regardless of the length of my menstruation.
