The Mira Fertility tracker is a device that monitors menstrual cycles and ovulation, helping people determine when they are more likely to conceive. Here, we review the tracker’s cost and effectiveness.

The Mira Fertility Tracker is a Food and Drug Administration (FDA)-listed and CE-registered electronic device that measures concentrations of certain hormones in a person’s urine to predict the time of ovulation.

These hormones are luteinizing hormone (LH) and estrogen. High levels of LH cause the ovaries to release an egg and stimulate the corpus luteum, which is a cyst that forms after ovulation and makes progesterone. Estrogen helps regulate the menstrual cycle.

Mira states that its fertility tracker is 99% accurate in determining ovulation.

Before purchasing the Mira Fertility Tracker, people may wish to consider the product’s advantages and disadvantages:


  • tracks LH and estrogen concentrations and fluctuations
  • small and portable
  • noninvasive


  • costs more than other over-the-counter ovulation trackers
  • potential syncing problems between the tracker and Mira App
  • online reviews mention unresponsive customer service
  • requires testing up to 20 times per cycle, which can be very expensive as the company sells the wands separately

Mira says that any person who ovulates can use its fertility tracker. The company claims that its fertility tracker can help people of any age conceive if they menstruate.

Additionally, unlike some other fertility trackers, Mira states that this product is suitable for people with irregular menstrual cycles or conditions such as polycystic ovary syndrome (PCOS) or endometriosis.

The company states that the tracker is suitable for people with these conditions because it measures hormone concentration levels. Once the tracker establishes a person’s baseline hormone levels, it can alert them when those levels increase or decrease.

However, people with irregular menstrual cycles, PCOS, or endometriosis may need to track their hormone levels more frequently than people with regular menstrual cycles.

Also, people with PCOS can have elevated LH levels without experiencing a surge — in other words, their baseline LH levels are high. This is why urine tracking may be less accurate in this group.

There have been no scientific studies investigating whether or not the Mira fertility tracker accurately indicates ovulation for people with these conditions.

It is important to note that the Mira is not an FDA-approved device for contraception. People may wish to use other methods to prevent pregnancy.

Ovulation trackers measure concentrations of LH in the urine to identify when a person is most likely to be ovulating. Typically, the body produces the most LH 24–36 hours before ovulation.

The Mira Fertility Tracker includes an analyzer, which is an oval, pod-shaped device that syncs with the Mira App and uses artificial intelligence to track hormone patterns.

The analyzer device works like a pregnancy test. Those using the Mira system dip a disposable test wand into their urine sample, then insert the digital end of the wand into the analyzer. The analyzer device then evaluates hormone levels in the urine and sends its findings to the Mira App. High levels of LH in the urine may indicate ovulation.

Research states that the accuracy of over-the-counter (OTC) ovulation predictor test kits can range from 19–99%.

A 2021 study suggests that Mira has a similarly high accuracy of predicting ovulation as the Clearblue Fertility Monitor. Mira itself states that its product is 99% accurate, but the relevant study is only available upon request.

However, it is worth noting that some people may have LH surges without ovulating. This is more likely if a person has infertility.

The Mira Fertility Tracker starter kit comes with all the necessary equipment to start tracking a person’s fertility.

The kit includes:

  • the Mira fertility analyzer
  • a carrying pouch
  • a charging cable
  • a user manual
  • 10 single-use Mira fertility plus test wands
  • 10 urine containers
  • step-by-step instructions

People will also need to download the Mira App, which is available on iOS and Android devices. The Mira Fertility Tracker automatically syncs with the Mira App to give people a report of their hormone levels.

The company also offers several other kits:

  • MAX kit: This kit contains an analyzer and 10 MAX wands which may have a slightly higher sensitivity to LH surges.
  • Clarity bundle: This kit contains an analyzer and 10 ovum wands which may predict the length of time until menopause.
  • Confirm bundle: This kit contains an analyzer, test wands, and Confirm wands that test for progesterone levels.

Mira offers several kits that bundle the fertility tracker and wands into a less expensive package. These kits include:

Warranty and returns

Mira ships worldwide. Shipping for orders over $148 is free.

The Mira Fertility Tracker starter kit has a 90-day money-back guarantee and a 1-year limited warranty. The test wands are not returnable or refundable.

Additionally, the company offers a full refund if a person uses the Mira Fertility Tracker for 3 months and the tracker does not detect any LH surges.

The following steps describe how to use the Mira Fertility Tracker:

  1. Urinate in a cup, then insert a testing wand into the urine for 10 seconds.
  2. Remove the cap from the digital end of the wand and place it on the end that was in the urine.
  3. Insert the wand into the analyzer component.
  4. Wait 15 minutes.
  5. Read the results on the Mira App.

Those who wish to track their fertility should start doing so about 5–6 days before their anticipated time of ovulation and at the same time each day.

The Mira App saves the ovulation data so that people can notice patterns over the course of their menstrual cycles. The Mira App and product can also track basal body temperature and menstrual cycle start and end dates.

At the time of publishing, Mira does not hold accreditation with the Better Business Bureau (BBB). The BBB gives the company an C+ rating, but customers give it an average rating of 1 out of 5 stars.

Of the reviews on the BBB website, one customer states that they did not receive their product and were denied a refund on shipping when Mira sent a replacement device. Another review states that the customer had difficulty syncing the device with the Mira App and did not receive a response from the company when the device stopped working.

However, reviews on the Mira website state that the tracker provides more information than similar products. Others say that the tracker is easy to use and gives clear results.

Here we answer some common questions about this product.

Is the Mira Fertility Tracker good?

The Mira Fertility may be a good option for people who are looking for more detailed hormone tracking. The company also states that it is accurate for people with PCOS and irregular periods, unlike many other trackers.

What is the success rate of the Mira Fertility Tracker?

According to Mira, the Mira Fertility Tracker is 99% accurate at detecting LH surges, which can indicate ovulation.

However, people should not use this device as a contraceptive method. To prevent pregnancy, people can use hormonal birth control, such as the pill, or nonhormonal birth control, such as condoms and sponges.

Learn more about the different birth control options here.

What is the difference between Kegg and Mira?

Kegg monitors cervical fluid to predict ovulation, whereas Mira uses urine to detect LH levels.

Research has found that women’s own interpretation of ovulation when analyzing cervical fluid matched hormonal analysis 80% of the time.

Is Mira better than Clearblue?

According to a 2021 study, Mira and Clearblue have comparable levels of accuracy.

The Mira Fertility Tracker calculates LH and estrogen concentrations and fluctuations to track ovulation and indicate fertile days. The company recommends that people use the tracker 5–6 days before their expected time of ovulation and at the same time every day.

However, people should not use this device as a method of contraception. They should discuss birth control options with a healthcare professional to prevent pregnancy.
