alto baby ,


I’ve been using this app (and previous versions of it) since 2011. When I started using the app I added all of my old data from previous months. I still have all of my old data back to late 2010. Fertility Friend has been invaluable for tracking my cycles, bbt, opks and then throughout my IVF journey. I now know my very own implantation signs because of the notes I took in this app and have been able to identify chemical pregnancies as they happen (implantation sign one day, positive test positive test the next, then sadly negative, but then I got pregnant without IVF and caught it on cycle day 23!).
I’ve used both free and full versions and really love it! FF has come with me through several phones!

I have two beautiful daughters because of this app.

I started writing this review in July 2018, but apparently never posted it:

“Fertility Friend was invaluable in helping me conceive my two youngest, and hopefully will be soon helping me conceive my next child. Unlike other period tracking apps, FF actually tracks *your* cycle, not an arbitrary average number. I have PCOS so I have very irregular and unpredictable periods, usually 40-70 days in length, and other apps start screaming at me that I’m late if I haven’t logged a period by CD28. Fertility Friend does no such thing and I am incredibly grateful for that.”

As of today, 27th February 2019, I can say that FF has actually helped me conceive once more!

Conceived twice first cycle using!

I loved this app. It was great to help me understand my cycles and what my body was up to. I have PCOS, irregular cycles and extremely long cycles. With my second baby, we tried for 11 months. I was then introduced to FF, and the first month using it, we conceived my second child. Four years later and we started trying to conceive and started with FF straight away. I thought it would take ages again, but first month of tracking with FF, first month of TTC, and I got a positive pregnancy test in my first cycle! Wouldn't hesitate to recommend!
