Great for irregular cycles and specific symptoms

I love this app. It’s not as slickly designed as other fertility apps, and that might put you off, but it’s the most flexible and most scientific of any of them. You can even pick the analysis method that predicts ovulation (eg FAM, cutting edge research, etc). It taught me a lot about the important of fertile cervical mucus and has been very helpful in tracking my irregular (PCOS) cycles. I appreciate the granularity of symptoms and ability to track your own particular ones and add your own. The only thing I don’t like is feeling judged when it says my temps are out of their normals... I wish there was a box you could tick to say you have PCOS and then it wouldn’t accuse you of mis-measuring your temp or being abnormal.

Perimenopause use 👍🏼

I've been using this app for several years through trying not to conceive, trying to conceive and fertility treatment (failed). I let my membership lapse after I started getting perimenopausal symptoms (I'm 40) and went on the quest to try menopause specific trackers. Eventually I rejoined fertility friend as it allows me to track MY personal symptoms by inputting them into the app myself. As with gynaecological and fertility issues, having an accurate diary of each day and trend reports to hand can help clinicians to identify the issues and get you the help you need earlier. Keep up the great work FF ❤️

Realistic and educational

In my nearly 4 years of ttc, I’m sorry I found this so late. It doesn’t look as user friendly and appealing as some of the others, but it is so much more realistic and doesn’t give you false hope like many others do, it is honest and seems more scientific, which appeals to me. Helps you to learn about your body and the changes you experience throughout your cycle, and the charts show all of your info in one place which is easier to interpret. It could look a little more up to date, which is the only reason I haven’t given 5 stars. So glad I found it and would recommend to anyone trying to conceive or who just wants to understand what’s going on in there every month!
