Our users are loving Mira

Mira has been the easiest and the least stressful test of the ones I have tried (Modern Fertility and Proov). Mira ensures greater accuracy since you don’t need “line-eyes” or to take a range in uncertainty with visual biases.

Review by S B.

I have been using various ovulation trackers for 2 years and Mira is by FAR the most accurate and easy to understand. I have recommended Mira to many of my friends who are ttc. Thank you, Mira!

Review by Nicole K.

After 7 months of trying to conceive with other mainstream tracking devices I decided to purchase Mira. One cycle in I conceived. I am now 4 months pregnant and extremely grateful. Nothing more to say :) Best decision I ever made in regards to conceiving was purchasing this device.

“The Mira Fertility Tracker offers excellent quality and accurate results at the patient's fingertips. As a health provider, I find that Mira’s quantitative measures far outweigh most qualitative over-the-counter kits. Mira is far more useful in clinical applications. We utilize Mira with our patients to help them successfully monitor, track and succeed in achieving pregnancies.”

Erin Foran Wolff, MD

Partner at Mira. OB/GYN, Reproductive Endocrinology. FACOG.

“As a fertility specialist, I was used to seeing my patients’ hormone results only twice per cycle. With Mira, I can see hormone patterns throughout many days of the cycle, over multiple months. This has provided clinical insight I have never had access to before, and allows me to tailor treatments in a much more individualized way. This personalized approach has helped patients become pregnant at significantly higher rates than standard, traditional, and generic fertility protocols.”

Gary S. Nakhuda, MD

Research collaborator at Mira. OB/GYN, Reproductive Endocrinology. FACOG.

"From my perspective as a reproductive endocrinologist and fertility specialist, Mira is a game-changing tool for patients and clinicians. With the convenience of home urine testing, the quantitative data of a laboratory blood test, and an informative and engaging app for hormone tracking—it seems to be the best of all worlds to improve the patient experience and optimize treatment outcomes. We are actively pursuing approaches to incorporate Mira into fertility treatments to reduce the burden of unnecessary blood tests and clinic visits.”

Thomas Bouchard, MD

Research collaborator at Mira. The University of Calgary, Department of Family Medicine.

“The MIRA monitor is a promising option for fertility monitoring. The ability to test on any day and at various times as needed, as well as the ability to detect when hormones change during various circumstances like the postpartum period and irregular cycles, will be a welcome advantage for the future of fertility monitoring.”

“As female hormonal levels change according to the menstrual cycle, the knowledge of hormonal event such ovulation renders women the confidence and freedom in decision making when a reliable home test device is available.”

Dr. Marc Sklar

“My favorite way to track ovulation right now is Mira Fertility. It is high lab-grade quality hormone testing at home. My favorite thing about this technology, the App, and the whole system is that it really takes the guesswork out of ovulation tracking.”
