Hormone monitoring has been stuck in the 80s since, well, the 1980s…
That ends today, with the launch of Mira’s Ultra4 Kit.
Women tracking their fertility have long faced a frustrating truth: traditional ovulation prediction kits (OPKs) cater to regular cycles, provide non-specific results (smile or frown, two lines or one), and leave users unable to observe long-term trends.
For those trying to conceive (TTC), customers using Mira’s Ultra4 Kit have a 10x higher pregnancy success rate than the analog calendar method.
And for those navigating hormone-related conditions, symptoms, PCOS, or menopause, the Mira Ultra4 Kit is the best hormone tracking kit on the market to understand and address the underlying causes.
Of course, these are big claims…
That’s because their Ultra4 Kit is the first hormone monitor kit on the market to measure and analyze all 4 key reproductive hormones using:
- lab-grade fluorescent technology, and
- AI-powered data synthesis
…to give women personalized, ongoing insight into their bodies so that they can take control of their journeys.

Stop Wasting Your Time With Yesterday’s Technology
Unlike their competitors’ antiquated nanogold technology from the 80s, Mira’s Hormone Monitor uses lab-grade fluorescent technology with up to 99.5% accuracy, the standard in clinical settings. Mira’s monitor is 7× more accurate than other fertility trackers and up to 6x more sensitive… in short, it detects subtle hormone shifts that the others could easily miss.
As the #1 Hormone Monitor in America, Mira is praised across the industry:
- Founder Sylvia Kang makes Inc’s Female Founders 250 List
- Mira Joins Fast Company’s World’s Most Innovative Companies
- Rated Healthline’s Best Fertility Monitor
- Chosen by 50+ leading universities & clinics to conduct research
The Ultra4 Kit further elevates the hormone monitor’s tracking capabilities with FSH monitoring.
For Women Trying to Conceive
“Am I actually ovulating?”
“Are my hormones normal?”
“Is low progesterone preventing pregnancy?”
Mira can help answer these questions.
By tracking FSH, LH, E3G, and PdG levels over time, the Ultra4 Kit paints a precise picture of your complete cycle from start to finish, not just ovulation itself.
The result?
Mira’s hormone monitor helps people conceive 10x faster than the traditional calendar method, a success rate that rivals IVF.
“After 8 months of trying and no clear answers, I felt completely defeated. Mira showed me I wasn’t ovulating regularly… and that changed everything. With that insight, I adjusted my timing and supplements and got pregnant two months later.” -Daisy
Navigating PCOS, Menopause, and Hormone-Related Symptoms
Up to 70% of women with PCOS remain undiagnosed. The onset of peri/menopause remains impossible to predict. And we all would like to understand whether hormones are causing our bloating, fatigue, or mood swings.
Mira’s Ultra4 Kit doesn’t just measure hormones in isolation, it shows how your four key fertility hormones (FSH, LH, E3G, and PdG) interact. This Hormonal Fingerprint™ reveals imbalances and can flag early signs of PCOS, menopause, or cycles where ovulation never happens.
The demonstrated proof of efficacy:
- Mira was ranked the #1 test for PCOS by Medical News Today
- 91% of people using Mira’s hormone monitor uncovered the root cause behind their hormone-related symptoms
- 84% of people felt relief after defining their stage of menopause with Mira

Mira’s Specialized (Yet Simple) Approach to Hormone Health
Simply dip an Ultra4 wand in a fresh urine sample, insert the wand into the monitor, then wait 16 minutes for results to appear in the Mira app.
While you wait, Mira’s hormone monitor uses proprietary technology to decode your cycle in greater detail through:
- 4D Ovulation Profiling™ gives you the if, when, and how of ovulation (no more guesswork!)
- Hormonal Fingerprint™ captures personal patterns in hormone fluctuation over time
- Egg Count Intelligence™ assesses egg health and ovarian reserve
- Egg Prep Scan™ scans for early follicle activity (necessary for ovulation) to catch potential anovulatory cycles
- Hormone Balance Check™ monitors LH:FSH and E3G:PdG ratios to identify imbalances linked to mood, energy, fertility, and more
Mira synthesizes, stores, and displays your results through their AI-powered app, fueled by insights from 1.4M real cycles (and counting). Not only does Mira generate personal insights and real-time charts, but it also reminds you when to test and creates professional, downloadable lab reports to share with doctors.
