Frequently Asked Questions on Fertility Apps

Do fertility apps work?

The most basic function of fertility apps is to track your monthly period and to give you an estimate of your monthly cycles in the succeeding months. As long as the fertility app can do this primary purpose, yes it does work. Other additional features of fertility apps are all subject to the brand’s claims and user’s discretion.  

How do fertility apps work? 

Fertility tracking apps tend to be referred to as ‘glorified calendar apps’. You merely record in the app’s calendar the first and last day of your period and then the app would use its built-in algorithm to calculate your next period. Putting your records consistently as the months go by allows the app to have a clearer idea of the length of your menstrual cycle. Calculating the fertility window would be estimated based on the middle of your menstrual cycle. Other apps use additional details to determine the day of your fertility by including them in the app’s algorithm and calculations. 

How correct are fertility apps? 

Despite the number of fertility apps on the market, only a handful of them use Evidence-Based Fertility Awareness-Based Methods (FABM). These methods have effects similar to other customary forms of birth control with ideal use. The facts rating of fertility apps based on a study evaluating 98 apps states that at least 1 app in each FABM category had a perfect score on accuracy. However, without proper training in the method, relying on these apps that use FABM may be insufficient to prevent pregnancy. 

Are fertility calendar apps accurate?

A study has shown that only 9% of the top 33 free apps have accurately predicted the fertile window, or did not mistakenly classify the fertile days as infertile. Pinpointing the exact day when a woman is fertile (also known as ovulating) is difficult, even with the use of an ovulation prediction kit. There are external factors that can be measured, such as basal body temperature, the thickness of cervical mucus, etc. However, other factors such as stress, intense physical activity, alcohol consumption, and hormonal irregularities, amongst others, may also play a role in affecting the day of ovulation. 

How accurate are fertility calendar apps?

A study conducted on 108 free fertility apps found only 20% to be accurate in determining the day of ovulation. However, it is important to note that fertility apps—as a general rule—tend to only indicate your chances of getting pregnant in the fertility calendar, whether it is high or low. Fertility calendar apps can only be as accurate as any Fertility Awareness methods, which when used with training and carefully followed instructions, can be 76-88% effective.  

At what time of the month is a woman fertile?  

You are most fertile just before or on the day of ovulation. Your ovaries release an egg to the fallopian tube and stay there for about 12-24 hours and this is the time where you are most likely to get pregnant. As a general rule of thumb, experts say that ovulation occurs in the middle of your menstrual cycle. So if your cycle lasts for 28 days, your day of ovulation would happen about 14 days before the start of your next period. 

Are fertility apps able to tell if I am infertile or not?

Infertility is defined as the incapability to get pregnant for at least a year (if you are younger than 35, 6 months if otherwise) of frequent unprotected intercourse. Getting pregnant needs both a male and female participant, and infertility may come from male or female factors about one-third of the time. Other times, the cause of infertility cannot be defined. Fertility tracking apps only keep track of your menstrual cycle and possible windows of fertility. Irregular menstrual cycles may be a cause of infertility. However, since regular menstrual cycles also do not guarantee that you are ovulating, it is best for you and your partner to consult with a medical professional should you have suspicions of infertility. 

What is Polycystic Ovarian Syndrome (PCOS) and can fertility apps determine them?

PCOS is a hormonal disorder where your ovaries develop many small collections of fluid (follicles) and fail to release eggs. It is also considered to be one of the most prevalent causes of infertility. The signs of PCOS are usually infrequent, irregular, or prolonged menstrual cycles. Some fertility tracking apps calculate your risk of PCOS based on the irregularities in your cycle. Nonetheless, there are available fertility tracking apps that are capable of predicting your period and fertile windows no matter how irregular you are. 

What does it mean if the fertility app is FDA approved? 

The Food and Drug Administration (FDA) is an agency responsible for evaluating the safety and efficacy of certain food and products in the USA. ‘FDA approved’ in essence means that the helpfulness of the product is more significant than the risks it poses upon usage. Hence, this label is often used for Family Planning Fertility Apps, as they are said to have better chances of being used as birth control despite the risk it poses to unintended pregnancies. 

What are the differences between Fertility awareness-based Methods (FABM), Fertility Awareness Methods (FAM), Natural Family Planning (NFP), and Rhythm Method? 

These terminologies are often used interchangeably but there are subtle differences and overlapping of definitions. Below are the specific meanings of these terms:Fertility Awareness Methods (FAM) is a large blanket of methods that recognizes when you are fertile and you prevent pregnancy by avoiding sexual intercourse or using a barrier method during the fertile days, or promote pregnancy by being intimate on your fertile days every other day, or much better every day.FABM is a specific language to refer to the different categories of methods that are used based on evidence and training. It has 5 different categories: Standard Days Method, Cervical Mucous Method, Basal Body Temperature (BBT) Method, and Sympto Thermal method. Natural Family Planning (NFP) is an older term for FAM or FABM, which requires abstinence as a method for preventing pregnancy in your fertile days. Although most of the FABM methods are considered NFP methods, abstinence is not essential for all FABM.Rhythm Method, or specifically known as Calendar Rhythm Method, merely keeps track of the days of your menstrual cycle in a calendar for at least 6 months. You then calculate for your fertile window based on your shortest and longest recorded cycle. You would then update these calculations each month by using the 6 most latest cycles.
