Customer Reviews

Brilliant app just a few minor amendments

App is generally brilliant for the charting and info etc.
For VIP functions the buttons are a little confusing and hard to find. For example I am in the forum and keep accidentally clicking "done" which exits the whole forum function and end up having to go through all the different pages to go back to where I was. It should really be renamed as EXIT. FF Facts/FAQs are also hard to find. Also haven't figured out how to amend what info on the chart I can share - a function I've played with on a desktop. Would be useful if it was available on the app!

Fantastic app

I bought this app when I was due to start natural cycle IUI and so needed to start tracking my fertility and identifying my ovulation day. Not only was the app really accurate at predicting ovulation and period dates (which helped with planning my life around IUI treatment weeks/months in advance) it helped me get more in tune with my body overall. I fell pregnant on the second round of treatment (I also used an ovulation predictor kit to pin point ovulation day). This app also took the stress out of remembering dates and putting notes in calendars too ! And the helpful daily tidbits were really reassuring and educational.


After not getting pregnant in five years I downloaded the free version of fertility friend. It gives a month of all the vip benefits and then goes to basic. I did that for a month and missed all the other little analysis and predictions so paid for a year. Anyway just five cycles in and I am unbelievably proud to say am now pregnant. This app is spot on with tracking and timing ovulation and periods and I'm positive I wouldn't be expecting now without having had it!! Don't hesitate to purchase ⭐️⭐️💫⭐️⭐️
