Mira Launches Ultra4™, the First At-Home Hormone Monitor with Lab-Quality Insights

Mira, a hormonal health company, has launched Ultra4™, the first at-home hormone monitor designed to provide lab-quality insights. The new device measures four key hormones - FSH, LH, E3G, and PdG - using a single wand and a 16-minute test, allowing people to monitor their entire cycle from home with the same precision previously available only in clinics. From ovulation strength to hormonal balance, Ultra4™ offers a comprehensive view of reproductive health.

By tracking all four hormones throughout the cycle, not just during the fertile window, Ultra4™ adapts to each user’s unique biology and provides a complete hormonal profile. This broader perspective helps users identify irregularities, spot imbalances, monitor shifts over time, and better understand their reproductive journey, whether they are trying to conceive, managing PCOS, or approaching menopause.

Ultra4™ stands out as the only at-home tracker powered by fluorescent technology, the same method used in clinical laboratories. This makes it up to seven times more accurate than other fertility trackers on the market and sensitive enough to detect subtle hormonal shifts that many consumer devices miss. Users also have the flexibility to test on any day of their cycle - or multiple times a day - with personalized guidance delivered through Mira’s AI-powered app.

The device introduces several new features. Its 4D Ovulation Profiling™ models the full hormonal ecosystem to predict when ovulation may occur and assess its viability. Hormonal Fingerprint™ establishes a personalized baseline of hormone trends over time to highlight irregularities or early signs of perimenopause. Egg Count Intelligence™ tracks FSH daily, providing at-home insights into egg health and ovarian reserve.

“When we launched Mira, it was with a single hormone and a single goal: help women understand their fertility better,” said Sylvia Kang, CEO and Co-founder of Mira. “But users kept asking harder questions - about irregular cycles, missed ovulation, egg quality, and hormonal balance. Ultra4 is our answer to those questions. It reflects everything we’ve learned in the past seven years from listening to our community.”
