Track your cycle with the Ultrahuman Ring. Identify menstrual, follicular, ovulation, and luteal phases using biomarkers like temperature, RHR, and HRV.

CONCEPTION

Plan smarter with fertility insights

The Ultrahuman Ring predicts your 7-day fertile window by analyzing biomarkers to pinpoint ovulation, helping you plan your reproductive journey with confidence.

How your Fertile Window is predicted

The 7-day fertile window is predicted by tracking biomarkers like skin temperature, RHR, and HRV throughout the cycle. These patterns help estimate fertile days before ovulation. Accuracy improves as more data is collected and analyzed over time.

Decoding your cycle with temperature

Subtle temperature shifts tell a powerful story. Throughout your cycle, these changes reflect hormone regulation, metabolism, and recovery. Understanding these trends provides deeper insights into how your body adapts, rebuilds, and performs during each phase.

Tracking HRV decodes your cycle by revealing hormonal shifts. Higher HRV shows resilience in the follicular phase, while luteal dips reflect increased demands. These patterns reveal how stress, recovery, and hormones influence your well-being.

Some description

A window into your hormonal shifts

RHR offers insights into cycle health, trending lower in the follicular phase for recovery and rising in the luteal phase with hormonal and metabolic changes. Tracking RHR reveals how your body adapts, shedding light on energy, readiness, and balance
