Fertility tracking apps can help you track your menstrual cycle and determine when you are ovulating. Women typically use fertility tracking apps or ovulation apps to understand their menstrual cycles further to facilitate or prevent pregnancy. Each fertility tracking app is a little bit different, offering unique features. Below, we’re sharing some of the best fertility tracker apps and more information on how they work.
There are several different fertility tracking apps that help users calculate when they are ovulating.
Fertility tracking apps work by interpreting menstrual cycle data to estimate when a woman is ovulating.
It is safe to consider data from a fertility tracking app to be fairly accurate; however, it is important to remember that ovulation dates are only an estimate. If used for birth control, success rates vary widely from 75-99%.
Overall, the best ovulation tracker will vary from person-to-person. It is best to find one that you find easy to use with features that work for you.

Ovia’s main dashboard offers users a fertility score to let them know how likely they are to get pregnant based on where they are in their cycle.
It also offers a fertility forecast, which gives you an idea of how fertile you can expect to be in the coming days and when you can expect your fertile window to fall. In addition, you can plug in different information to help make your fertility tracking more accurate, such as your sleep, nutrition, alcohol, mood, and whether you had sexual activity.
Overview: Clue has a simple, easy-to-read dashboard that predicts fertility based on the information you plug into the app, such as whether you are on your period and how you feel. You also can choose the calendar view, in which your menstruation dates and predicted ovulation for the month are highlighted.
In addition, with a subscription, you’ll be given full access to in-app articles that provide additional information about women’s health, fertility, menstruation, and pregnancy.

Partners can “link up” through the app to get a complete picture of their fertility as a couple. This could be considered one of the best apps for getting pregnant, since it allows couples to work together to understand fertility.

Why use a fertility tracking app?
There are several reasons why women choose to use fertility tracking apps. First, you may be trying to get pregnant and want to keep a close watch on your cycle to pinpoint the best time to attempt conception. Or you may want to do the exact opposite — by knowing when you’re ovulating, you can avoid getting pregnant by abstaining from sex during that time or making sure to take extra precautions.
Either way, a fertility tracking app is a tool to help give you a clearer picture of your menstrual cycle to help predict what you can expect in the months going forward.
Some benefits of tracking your cycle include:
- It can help you predict when your next period will start and end.
- It might help facilitate or prevent pregnancy by estimating when ovulation will occur.
- It is useful in tracking irregular cycles if you’re concerned there may be an issue.
It is important to understand that fertility tracking apps use an algorithm to determine your fertility based on your information. Therefore, you have to stay on top of entering data each day for your data to be as accurate as possible. Even so, you shouldn’t rely solely on an app (especially if trying to prevent pregnancy).
The fertility awareness method
For the most accurate fertility data, women should learn how to track their cycle and recognize fertility signs through the fertility awareness method. If you know what types of signs to look out for to predict fertility, you can use tracking apps simply to keep track of your data so that you can interpret the information yourself.
The success rate of using the fertility awareness method as birth control can be as high as 95-99% when done perfectly, meaning consistent and thorough tracking every day and correct interpretations, but studies have found that the average user's success rate is only 76-88%. Therefore, it is not recommended by healthcare providers to use it by itself as a form of contraception. Condoms or other birth control methods are recommended in addition to the fertility awareness method if the goal is to prevent pregnancy.
If trying to conceive, there is less risk for using the fertility tracking method since an inaccurate reading would mean no pregnancy, and they can try again next cycle.
Are fertility tracking apps accurate?
Fertility tracking apps vary greatly in their accuracy and technology. They are useful tools, but users should be aware that they may not be entirely reliable. You shouldn’t solely rely on a fertile window prediction from an app when trying to get pregnant or prevent pregnancy, since it may not be fully accurate.
What fertility tracking app is most accurate?
All fertility tracking apps function a little differently, so it is hard to say which one is the most accurate. Some apps come with additional devices, such as thermometers for testing body temperature and urine test strips to provide more accurate fertility data.
How does a fertility app know you’re ovulating?
Fertility apps use data you’ve entered about your menstrual cycle to estimate when you will probably ovulate. The more data you enter, the more accurate your estimate will be. For example, if you only enter the days of your period, then the app will simply calculate it based on how long your estimated cycle is. If you also enter in additional data such as your cervical mucus and your body temperature, this can help to more accurately determine when you would be ovulating.
