Customer Reviews

Very pleased

I like this app a lot. It's so informative, and automatically compares your experience statistically to other women's so that you know what to expect and what is normal when you're trying to conceive. It's a great tool for whatever you need it to be, whether that's just tracking your period or for keeping tabs on every single feeling you are having. I also really like the user interaction format - even on apps like babycenter I got VERY tired of the bullying and negativity and bickering that went on in the comments section. This one is totally anonymous and everyone is so positive and sweet. There are relevant articles and encouragements that show up on your homepage that are custom tailored to the information you record on the app, which is refreshingly personal. I like that you can view your fertility probability in calendar, chart or score form too - there really is something for everyone. Five stars!

The best app to help you conceive !

I am a mother of 2 boys, and now trying for my 3rd. This is my first time using this app thanks to a friend that recommended it to me. It's 100 percent accurate with my period and I'm sure also with my fertile Windows. I love how their is also a anonymous chat you could ask other and also answers questions for women like you trying to conceive. I am addicted to it and am on this everyday! Their are articles you could read about a lot of different things of course in regards to baby making and staying strong and healthy for preparing for your baby. I have never felt the need to EVER rate and write a review on any app I have downloaded. But this deserves my undecided attention to tell others how great and happily satisfied with this app. What are you waiting for ?! Go download !

Such a better app than what I had been using

Beautiful app! Just wish we could customize the order of things in our journal (such as have notes or med at top)...and have it save stuff automatically or ask to save when you click out if journal and forget to hit save.

Also wish from within journal you could expand on each section and what they mean... For instance, I can never remember which discharge is more fertile or the details on cervical position. I'd like to be able to click that area and had it open up a little informational screen about that section.

I also would like to see a little integration with hormones and how they affect the day today. I love using the app Hormonology but it would be awesome to have that in with this.
