Thank you FF for my baby girl

This app is truly amazing. I am able to monitor, track, and predict my cycle. I am so happy to have come across this app. I had no idea something like this was out there in the app world. I was just looking for a regular menstrual cycle app that was a little bit more in-depth than the one I had to help us get pregnant.
There are classes and actual test you take to make sure you get what is being thought. There are graphs, schematics, charts, Q and A’s, in-depth questions that are relevant to your cause. You can use the free app, which is perfectly fine and just as good, or you can upgrade for an annual fee. I did the free version, then upgraded for 1 year when we decided to get pregnant. The extra features helps a lot to predict the best times to make a baby.
FF was extremely helpful in helping us get pregnant with our second baby. We started trying in June and was pregnant in December. For me, the first three months was studying, reading, prepping and trying to get the timing right and the next three months, were hitting those 3-4 fertile days, and nonchalantly waiting for results. Good luck!! May the Odds Be Ever in Your Favor!! Also, I find that including the day after the last ovulation day is helpful.

Best Available Option to Track Your Cycle

This app has truly thought of it all. The features are all encompassing. You can literally track anything and everything with a daily cycle. There are many medications and supplements (the most popular) already in the list for ease of adding them. Have something else to track? For example I drank Raspberry Tea while TTC, you can choose to add whatever you want to your list. From cervical position and mucus to your mood and feeling of bloatedness. It literally has thought of everything. Until this app I had a hard time tracking my "baseline" temp but this does all the calculations for you to the tenth or to the hundredth depending on the type of thermometer you have (I HIGHLY RECOMMEND TEMPING VAGINALLY FOR THE MOST ACCURACY). It also provides you with daily suggestions based on your input and predictions on ovulation/ period and when to test. You can overlay your chart or look for charts like yours. It's incredibly well thought out. Kudos to the creators.

Most accurate

We’ve been TTC for a year now, and I have been diligently tracking my cycles in 6 (!) apps (I only used 3 apps the first 6 months and then added Fertility Friend plus 2 others). I’ve tried every ovulation/cycle tracker app in the App Store, so I’ve done my research.

OvaGraph was generally my favorite BBT app, but I have to admit that Fertility Friend has been the most consistently accurate when it comes to detecting my ovulation. More than any other app, FF seems to actually ‘listen’ to the information I log each day and never fails to match up with what I believe my body is saying (as opposed to other apps that are generally accurate but not precise). My only ‘complaint’ would be that it’s not as ‘pretty’ or modern as other apps, but at the end of the day, it’s certainly the most precise - and that’s what matters.
