Countless women strive to have a thorough understanding of their menstrual cycle in order to optimize their fertility and increase their chances of conceiving.
One of the best ways for women to further grasp the individuality of their own menstrual cycle as well as reduce the overall amount of time spent trying to conceive is through the use of an ovulation tracker.
Ovulation trackers are available in many forms and most women tend to use ovulation predictor kits or those that are based on wearable sensor technology.
In this article, we’ll review the 3 best ovulation trackers and discuss the major pros and cons of each type.
TL;DR: What is the Best Ovulation Tracker?
- Mira Fertility Tracker is the best ovulation predictor kit that comes in the form of a urine-based test paired with an analyzer that tracks your numeric LH and estrogen hormone levels. These levels are then used to identify when a woman’s most fertile days occur.
- The best fertility bracelet is the Ava Fertility Tracker. It tracks 5 major physiological parameters including skin temperature, resting pulse rate, heart rate variability ratio, perfusion, and breathing rate. This data is then analyzed by the Ava app to detect a woman’s 5-day fertile window.
- The OvuSense Fertility Monitor is the best ovulation monitor on the market. Women insert the OvuCore sensor vaginally and then wear it overnight to continuously measure their core body temperature (cCBT). The data obtained from these readings is then analyzed by the OvuSense app to predict ovulation up to 24 hours in advance with 99% accuracy.
Femtech (female technology) encompasses a wide range of technology and devices that are designed to support women’s health.
In more recent years, Femtech has become a critical component of women’s reproductive health, most notably in the realm of understanding each woman’s unique menstrual cycle and how it may affect their chances of conceiving.
Numerous tests and trackers have been developed to help detect women’s fertile windows and pinpoint ovulation. Examples of Femtech devices created for this purpose include:
- Smartphone apps, such as ovulation predictors and menstrual cycle calendars
- Wearable devices, such as ovulation bracelets
- Insertable devices, such as vaginal monitors
Let’s take now take a quick look at how these tests work and the types of data their predictions are based upon.
Different ovulation tests vary in their approach to detecting a woman’s fertile window and pinpointing the exact day of ovulation.
Most tests use one of the following ways for estimating or detecting ovulation and the overall likelihood of conception:
- Urine Test – This form of testing is used to detect numeric hormone levels, such as Luteinizing Hormone (LH) and estrogen. A sharp LH surge indicates that ovulation will occur within the next 1-2 days. Additionally, an increase in estrogen is also linked to a woman’s fertile window.
- External/Wearable Device – A device is worn externally that monitors body temperature and in some cases additional physiological parameters, which fluctuates throughout a woman’s menstrual cycle and indicates whether or not a hormonal surge has occurred or is nearing.
- Basal Body Temperature (BBT) – Women record their basal temperature immediately upon waking with an oral thermometer and track their readings daily throughout the month in order to determine the exact date of ovulation. This form of testing may also be used for predicting their upcoming fertile window
- Internal Device (Vaginal) – A device is inserted vaginally that records core body temperature data. This form of temperature-tracking is more accurate than that of Basal Body Temperature (BBT) or readings taken externally, such as on the wrist or under the armpit.
Best Ovulation Tracker
Trying to decide which ovulation tracker is best is a hotly debated subject and relies upon several factors.
While some women prefer to use standard methods of testing, such as relying on urine tests or tracking BBT, other women may prefer the use of wearable devices that are easy to use, are non-invasive, and reduce some of the stress that’s associated with taking manual measurements.
However, there are women who may prefer the use of vaginal monitors which typically provide the most accurate and comprehensive results in comparison to other trackers but are slightly more expensive.
We’ll now review our list of the 3 best ovulation trackers currently available for women.
We’ve made sure to includes an ovulation predictor kit, an ovulation bracelet, and an ovulation monitor on our list for women who are interested in exploring the different options available for tracking.

Best Ovulation Predictor Kit – Mira Fertility Tracker
The Mira Fertility Tracker is an ovulation predictor kit (OPK) that allows women to test their quantitative estrogen and LH hormone levels from the comfort of their home.
Both hormones are correlated with ovulation and peak fertility and prior to ovulation, estrogen levels steadily increase and a sharp surge of LH indicates ovulation is about to take place within 1-2 days.
These numbers combined provide women with a 6-day fertile window that’s optimal for conception.
Mira recognizes that each woman has their own unique ovulatory patterns and that many women have issues with using standard fertility apps.
Most generic apps don’t take into account hormone levels, abnormal cycles, or other critical information that affect ovulation and impact trying to predict the optimal time to try to conceive.
Mira Fertility Tracker Options
Currently, there is 1 option available for the Mira Fertility Tracker – the Mira Fertility Plus Starter Kit.
This kit contains the Mira Analyzer and comes with 10 estrogen + LH testing wands. However, women can also purchase additional testing wands in sets of 20.
Here’s a closer look at what’s included in each starter kit:
How to Use Mira Fertility Tracker
The Mira Fertility Tracker is extremely user-friendly and the entire testing process takes no more than 20 minutes.
- First, you will need to collect a urine sample in the morning with one of the provided urine cups. Following the urine collection, you will then need to dip one of the testing wands into the sample for around 10 seconds.
- After dipping the wand into the urine sample, remove it and place it into the tracker for analysis. This process usually takes around 15 minutes to complete.
- Once the analysis has finished, the app will provide personalized information about a woman’s fertile window, such as their hormone baseline levels, and how their hormone surges correlate to ovulation.
This information is critical for knowing exactly when a woman should try to conceive and also enables women to have a better understanding of their own unique cycle.

“Ovusense has helped me to fully understand how my body is working and where we may have been going wrong previously… I would use Ovusense every time when trying to conceive”
“I started using the OvuSense device in January 2019 and my son was conceived on the fifth cycle. At 39 and 50 my partner and I had been having no success in conceiving and had begun to put it down to biology but using OvuSense allowed us to pinpoint ovulation and identify that I had a slightly short luteal phase. ”
“Taking my temperature any other way, never worked for me. I never knew if I was doing it right. But with OvuSense, it did all the hard work for me. Wearing the sensor every night was so simple. Doctors didn’t think I ovulated. I learned with OvuSense that I actually did ovulate and by the second cycle knew when to baby dance to try to have a baby.”
