Fertility Friend alerts you to fertile days and ovulation, highlights the most fertile days to conceive, and provides timely, personalized insights for conception and pregnancy planning.

Fertility Friend teaches you how to track fertility signs, explains what they mean, and clearly displays fertile days on an interactive fertility chart and color-coded fertility calendar.

Great app. I have downloaded many fertility apps and this is the only one that predicts ovulation / period based on my cycles I have entered rather than the average woman. It gives you loads of statistics about your cycles. The only criticism I have is the look is a little outdated and initially I found it a little difficult to navigate through the app.

Really love the app, having been using it for years at vip level, however this evening when i opened the app, all the colours on the charts have become muted and im now unable to distinguish my meds patterns as its all pale pastel colours. Im hoping is a blip on the software and will be resolved tomorrow as i need to be able to see at a quick glance which meds are due to be taken on rotation.

I suppose it might be acceptable but only if your aim is to get pregnant. what is the point of having a so-called "advanced" setting (which is recommended no less) that ignores cervical mucus data?? my cycles are regular but slightly on the longer side and this app is frequently entirely wrong about when I ovulated, usually confirming based on temperature alone and according to the rules of no method that I have ever come across. Dangerous if avoiding pregnancy.
