Ovulation tracker app helps a woman in keeping a track on her periods and ovulation. The best ovulation app helps you analyze the average length of your menstrual cycles which aids in either preventing pregnancy or in successful conception as per requirement of a couple. Ovulation tracker offers accuracy.

Talking about ovulation and period tracker apps, the reviews have been different. The reason behind this partial against and for is the accuracy of these apps in predicting the cycles and ovulation.

There are dozens of period trackers and online apps, which have gained popularity in the recent years. These apps provide estimates about the days that someone is most likely to or least likely to conceive and hence assist the couples in planning their family according to their needs. But just as the benefits, women should be aware of the limitations of applications too. Several apps and websites promise to calculate the woman’s most fertile phase, which can be off base too.

Let us say, for some women the apps are sometimes used as a way of avoiding pregnancy then tracking period is not a reliable method of contraception. Whereas women who are trying to conceive can use these applications as they are useful in tracking their menstrual cycle and fertile window.

How does ovulation tracker app work?

Apps like Ela, Life, Cycle, My Menstrual Diary, Eve and many more to add to the list are some of the applications available for tracking the menstrual periods.

Like in every app, the user has to feed the date of her last menstrual period started along with the duration of her cycle. By using these details, these apps then estimate the ovulation as well as the fertile window. For a woman whose cycle is of 28 days, her ovulation day will fall around day 14th. However, the length of the menstrual period cycle can vary from month to month. The apps consider the data insights of previous cycles to come up with a prediction for the next cycle. These applications usually add a few days around the woman’s peak fertility date and show a ‘fertility window’.

And after collecting the data from several previous menstrual cycles, some of the apps will analyze the average length of the cycles for determining the fertile phase. These applications are pretty accurate for the women whose periods are regular. But women with irregular cycles and those with cycle length of more than 35 days or less than 21 days, these apps are not of much help.

Most of the times, an irregular cycle is a sign that a woman is not ovulating but has irregular bleeding. So, even if the app is unable to determine the fertility window accurately for a woman, it can still help them to know that their cycles are not regular. A woman is advised to see a doctor if her cycles are irregular since very long.

So, apart from using the fertility tracker app, it is advised to use over the counter ovulation predictor kits, which are close to accurate in determining the ovulation date for women who have irregular cycles. The kits help in measuring an increase in Luteinizing Hormone (LH) in the urine.

Apart from using the OPK, a woman can also observe the changes in cervical mucus for determining when they are ovulating. Also, as sperm can stay in a woman’s body for around 5 days, having unprotected sex every two to three days is a way of increasing conception chances.

Period Tracker Apps for Preventing Pregnancy

Like some apps have disclaimers that applications cannot be used for avoiding pregnancy, it is not the case with all the apps. A cycle tracking or fertility tracker can be used effectively for preventing pregnancy very effectively. It helps a woman in identifying the ‘fertile window’ within their cycle. With such updates, it will be easy for women to avoid or achieve pregnancy by picking when to have intercourse depending on their family planning goals. This method can also fail due to the variation in woman’s menstrual cycle length.  So, for avoiding pregnancy, there are several successful contraception methods available.

One such app that has been utilized for both the purposes is ElaWoman app. The app claims to be 98.3% accurate in determining the ovulation of woman based on the details updated by her. The app is useful for tracking fertility and ovulation calculator, helps in predicting the best days and when to avoid sex for preventing pregnancy.

Women can find the best days and the fertile window for planning the pregnancy with the most accurate fertility prediction. Automated notifications help in tracking the ovulation in a seamless and easy way.  The app also provides five day and monthly fertility calendar views for knowing the fertile window as well as ovulation day along with the percentage chances of conceiving every day.

The app considers your past period calendar and the ovulation dates to have a better understanding of your upcoming fertility phase. These dates are based on the daily health meter logged in by the woman, tracking over 15 health parameters. These parameters include cervical mucus, Basal Body Temperature, cervical position, sleep, stress, weight and mucus.

An ovulation tracker is a helpful assistant but not a complete solution

Full-featured fertility and period tracker can help in tracking all the three data along with other things including mood and PMS symptoms. You need to feed the data in the app while in reality you have to check the cervical fluid along with body temperature and in a way, monitor your body. It implies that these apps act as assistants in your journey to conceive. Instead of you remember all the details; the app does it for you. They prepare data and color-coding calendars but it is you who has to differentiate between the fertile mucus and almost fertile mucus.

The apps are helpful in tracking menstrual cycle and every month they notify the users via reminders about their cycle. It is helpful in answering the most asked question ‘When was your last period?’ by the doctor. And for a woman who is expecting, knowing her last menstrual period date is sufficient for the app to calculate the fetus’s age.

Why ovulation tracking is not a perfect science?

The ovulation tracking or fertility tracking apps are purpose calendars. You are required to update your health log daily and accordingly the app calculates your most fertile days. Timing needs to be right as sperm can live up to 5 days in a female body but ovary releases an egg once a month. So, having sex four days or so before ovulation has good chances of leading to pregnancy.

But, unluckily, there is no method to predict when you are about to ovulate. The calendar can help as ovulation occurs about two weeks prior to the next menstrual cycle. This can get tricky as cycles vary in length thus, making ovulation prediction hard.

But the female body keeps dropping clues when ovulation occurs. The woman has to examine her cervical fluid, which gets stretchable and more slippery when ovulation happens. The other helpful clue is body temperature which increases half a degree or so after ovulation.

You can really mess with your cycle tracking if you have irregular cycles. Chances of having fertile days with your mensurational cycle are possible too so, in spite of taking chances it's better to use these apps.
