Ultrahuman Ring Air users are getting new, advanced ways to track their menstrual cycle, as the smart ring and wearable health brand launched Cycle and Ovulation Pro on Friday. The paid subscription offers menstruating users with irregular cycle patterns a more accurate cycle tracking tool. The Pro version is an extension of Ultrahuman's Cycle and Ovulation power plug, which is free for all Ring Air users.

The feature boasts an accuracy rating of over 90%, which was validated through equivalence testing standard analysis. The tool supports fertility planning based on a broad array of cycle types and is bolstered by accurate ovulation confirmation. Cycle and Ovulation Pro can detect patterns of cycle variability based on its temperature-sensing technology, allowing users to track their symptoms through a tagging mechanism for further insights.
To make the features within Cycle and Ovulation Pro possible, Ultrahuman acquired viO HealthTech, a women's health technology brand and maker of OvuSense, a fertility and cycle monitor. Ultrahuman uses OvuSense's temperature-sensing algorithm in its new fertility feature.

Ultrahuman is leveraging OvuSense's technology for Cycle and Ovulation Pro, which is designed for people with PCOS, thyroid disorders, endometriosis, or those whose periods don't follow the conventional 28-day timeline. It takes a user's continuous Core Body Temperature measurements overnight with .003 °C precision, according to OvuSense's website. This approach allows the OvuSense device to filter data and confirm ovulation with 99% accuracy.
The original OvuSense device worked by being inserted vaginally every night to monitor fertility. Ultrahuman has sidestepped this invasive process in fertility monitoring through its Ultrahuman Ring Air's temperature-sensing capabilities. OvuSense is trained on a dataset of over 260,000 cycles, according to Ultrahuman's press release, and validated in 13 peer-reviewed medical publications.
The algorithm uses temperature data collected by the ring to understand and predict cycle variability. Insights include information on ovulation timing, luteal phase, the absence of ovulation, and patterns related to PCOS or miscarriage risk, Ultrahuman said in the press release.
Ultrahuman CEO Mohit Kumar said the update combines top-tier hardware, software, and clinically backed algorithms in one wearable device.

The announcement comes several days after Oura, its top smart ring competitor, unveiled new women's cycle tracking features of its own. Oura's features are more focused on pregnancy and menopausal tracking.
For those interested in trying out Cycle and Ovulation Pro, the feature is available across the US, UK, EU, Australia, and Canada for $4 a month or $40 annually.
