Stop guessing with OPKs. Mira tracks 4 key hormones to reveal exactly when and how well you’re ovulating—even with low hormone levels, multiple LH peaks, and other irregularities.
Analyze relationships between key hormones to reveal imbalances that can affect ovulation and fertility, helping you plan conception with more confidence.
Discover your Hormonal Fingerprint™—a baseline to help track subtle changes overtime to identify anovulatory cycles and early signs of PCOS.

⁷Based on a 2025 lab study by Mira Labs comparing Ultra4 Wands to other popular at-home fertility trackers across LH, FSH, E3G, and PdG. “2× broader range” refers to Mira’s ability to detect both lower and higher hormone levels. Vary from 1.1× for PdG to 3× for E3G. Results may vary. Mira is not a diagnostic or contraceptive device.
⁸Based on a 2025 lab study by Mira Labs comparing Mira to other popular at-home fertility trackers. Mira detects LH at levels up to 4× more sensitive than other fertility trackers that allows earlier detection of the LH rise. Results may vary. Mira is not a diagnostic or contraceptive device.
⁹Based on a 2025 lab study by MiraLabs comparing Mira to other popular at-home fertility trackers for LH, FSH, E3G, and PdG. “7× more accurate” refers to average alignment with lab results (range 2×-18× for different hormones); “3× more reliable” refers to the average improvement in linearity (range from 1-4× for E3G to 4-6× for LH); and “up to 6× more sensitive” is based on lower detection limits (range from 1-2× for PdG to 6× for E3G). Individual results may vary. Mira is not a diagnostic or contraceptive device.
