Fertility trackers monitor menstrual cycles and ovulation to determine the most likely days a person will conceive. To calculate ovulation, these devices measure hormonal changes in urine or saliva as well as basal body temperature.

This article discusses what the Mira Fertility Tracker is, how it works, and how it compares with alternative products.

The Mira Fertility Tracker is a Food and Drug Administration (FDA)-approved 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.

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

Of the two 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. The other 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 easy-to-understand results.

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.

However, although the company states that the fertility tracker is suitable for people with PCOS and endometriosis, there have been no scientific studies investigating whether or not the tracker accurately indicates ovulation for people with these conditions.

The company says 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.

Mira states that the fertility tracker is not FDA-approved as a contraceptive device.

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.

Some research states that over-the-counter (OTC) fertility trackers that detect hormones in urine, such as the Mira Fertility Tracker, are a less invasive way of measuring LH levels. The study authors note that any fertility tracker that is sensitive to LH surges may accurately detect ovulation.

However, they also say 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.

Mira also sells the following products:

  • replacement fertility wands
  • fertility tests
  • male fertility tests
  • menstrual cups
  • fertility tea

At the time of publishing, the Mira Fertility Tracker starter kit costs $199.

Before purchasing the Mira Fertility Tracker, people may wish to consider the product’s pros and cons.

The Mira Fertility Tracker can track LH and estrogen concentrations and fluctuations in a person’s urine. The product is small and portable, and it offers a noninvasive way of indicating ovulation.

However, the device is more expensive than some other OTC ovulation trackers. Additionally, some customers have found it difficult to sync the tracker with the Mira App and found the customer service department unresponsive when wanting to discuss issues with the product.

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.

Mira ships worldwide. Shipping for orders over $149 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.

Affordable alternatives

People can also purchase more affordable ovulation testing kits. Ovulation tests that are sensitive to LH surges are more likely to accurately indicate when a person is ovulating.

However, unlike the Mira Fertility Tracker and similar products, these tests do not track quantitative LH levels. That said, people who use alternatives to the Mira Fertility Tracker can still do this over time. For example, they can test daily or twice daily and use their own methods of charting the results.

Some options include:

At the time of publishing, these kits have list prices of around $20.

Below are some frequently asked questions about the Mira Fertility Tracker.

Does the Mira Fertility Tracker work for people with PCOS?

Mira states that its fertility tracker works for people with PCOS, endometriosis, and irregular menstrual cycles. The tracker detects a baseline hormone level and alerts people when the hormone level increases, which can indicate that a person is ovulating.

However, no scientific studies have shown that the Mira Fertility Tracker accurately indicates ovulation for people with these conditions.

What is included in the Mira Fertility Tracker kit?

The Mira Fertility Tracker starter kit comes with a fertility analyzer, a charging cable, urine containers, and fertility wands. The fertility wands are single-use, but people can purchase more from the company’s website.

How accurate is the Mira Fertility Tracker?

Mira states that the Mira Fertility Tracker is 99% accurate at detecting 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.

Does insurance cover the cost of the Mira Fertility Tracker?

Mira accepts flexible savings accounts (FSA) and health savings accounts (HSA). People can purchase the tracker with their FSA or HSA debit card, or they can pay for the device using an alternative method and submit for reimbursement.

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.
