Ultrahuman, a global leader in wearable health technology, today announced its acquisition of viO HealthTech and the launch of Cycle & Ovulation Pro<\/strong> for Ultrahuman Ring AIR.<\/p>\n\n\n\n

Rolling out now in the USA, UK, EU, Australia, and Canada as a groundbreaking new plug-in for Ultrahuman Ring AIR, Cycle & Ovulation Pro boasts best-in-class 90%+ accuracy for ovulation confirmation.<\/p>\n\n\n\n

Most menstrual tracking platforms are built for women with regular 28-day cycles. In reality, the majority have diverse cycle patterns \u2013 and those with conditions like non-bleeding, PCOS, endometriosis or thyroid disorders often don\u2019t get an accurate or supportive experience. Ultrahuman\u2019s acquisition of viO is designed for them.<\/p>\n\n\n\n

Cycle & Ovulation Pro leverages an adaptation of viO\u2019s OvuSense\u2122 technology, taken from its class II medical device fertility and cycle monitor, and reconfigures it for consumer wellness tracking. The OvuSense\u2122 technology was developed over 15 years, trained on a dataset of over 260,000 cycles collected with medical-grade sensors, and validated in 13 peer-reviewed clinical publications.1<\/sup><\/p>\n\n\n\n

Cycle & Ovulation Pro features<\/h2>\n\n\n\n
\"Cycle<\/figure>\n\n\n\n

Cycle & Ovulation Pro is designed for the reality of human biology \u2013 not the hypothetical 28-day cycle. It complements Ultrahuman Ring AIR\u2019s existing free Cycle & Ovulation PowerPlug and adapts to the variability women experience throughout their lives, offering personalised wellness insights that reflect actual data rather than assumptions.<\/p>\n\n\n\n

    \n
  • The most accurate cycle tracking on a ring (>90% accuracy):<\/strong> Validated through rigorous equivalence testing using both LH and progesterone rise2<\/sup>, building on prior OvuSense\u2122 clinical studies3<\/sup>, now adapted for wellness.<\/li>\n\n\n\n
  • Fertility planning support for all women:<\/strong> Guidance for women with a wide range of cycle types, providing highly accurate ovulation confirmation.<\/li>\n\n\n\n
  • Cycle Flags\u2122:<\/strong> Uses your temperature data to suggest hidden patterns supporting better personal understanding of cycle variability.  Trends include early or late ovulation, short luteal phase, the absence of ovulation, and proprietary patterns that may be related to conditions like PCOS or miscarriage risk.4<\/sup><\/li>\n\n\n\n
  • Designed for diverse cycles:<\/strong> Works reliably for women who don\u2019t have a textbook 28-day cycle \u2013 including those with PCOS or endometriosis \u2013 in tracking and understanding their cycles.<\/li>\n\n\n\n
  • Symptom and lifestyle tagging:<\/strong> Enables women to log mood, symptoms, and behaviours in relation to cycle phases to help identify longer-term personal wellness trends.<\/li>\n<\/ul>\n\n\n\n
      \n
    1. The Cycle and Ovulation Pro PowerPlug is designed for general wellness use. The Cycle and Ovulation Pro PowerPlug and Ultrahuman Ring AIR should not be regarded as a substitute for professional medical diagnosis or treatment from a qualified healthcare provider. Always seek the advice of your doctor or other qualified healthcare provider with any questions you may have regarding your health, a medical condition or treatment options.<\/li>\n\n\n\n
    2. Accuracy was determined using internal equivalence testing standard analysis comparing OvuSense + Ring AIR output with a multi-hormone ovulation prediction method, and registered in the OvuSense Technical File. viO HealthTech is ISO 13485 and MDSAP certified as a medical device manufacturer.<\/li>\n\n\n\n

Front Bioeng Biotechnol. 2022 Mar 4;10:807139. doi: 10.3389\/fbioe.2022.807139. PMID: 35309997; PMCID: PMC8931469.<\/li>\n\n\n\n

    5. The original OvuSense\u2122 algorithm is FDA-cleared for intravaginal use (K122337) in viO\u2019s regulated product. In the Ultrahuman Ring AIR, the algorithm is adapted for general wellness use and is not FDA-cleared.<\/li>\n<\/ol>\n\n\n\n

      \u201cThis collaboration benefits from 15 years of clinically proven women\u2019s health expertise and applies it to the world\u2019s lightest smart ring. For the first time, best-in-class hardware, software, and algorithms with a clinical background come together in one wellness device. Our mission is to give women cutting-edge tools to optimise their health, combining clinical technology with comfort and style to deliver the most accurate women\u2019s health tool available,\u201d said Mohit Kumar, CEO of Ultrahuman. <\/p>\n\n\n\n

      \u201cWearables will shape the future of health\u201d, said Rob Milnes, CEO of viO HealthTech. \u201cWe\u2019re delighted to be able to bring OvuSense women\u2019s health insights to a significantly wider audience via the Ultrahuman Ring AIR.\u201d<\/p>\n\n\n\n

      Backed by 15 years of R&D<\/h2>\n\n\n\n
      \"C&O<\/figure>\n\n\n\n

      Cycle and Ovulation Pro uses an adapted temperature-sensing algorithm originally developed for viO\u2019s OvuSense\u2122 fertility monitors. When applied to the Ultrahuman Ring AIR, it enables adaptive, cycle-aware tracking via the finger for consumer wellness tracking.<\/p>\n\n\n\n

      It allows for personalized insights that adapt over time \u2013 enabling a better understanding of how individual cycles evolve across life stages and contexts.<\/p>\n\n\n\n

      Unlike traditional period trackers, which rely on static averages and calendar-based predictions, Cycle & Ovulation Pro collects physiological patterns and temperature biomarkers captured passively via the Ultrahuman Ring AIR \u2013 framing this clinically validated heritage as a wellness feature for everyday use.<\/p>\n\n\n\n

      Inspired by OvuSense\u2122: Proven Algorithmic Foundation<\/h2>\n\n\n\n

      Cycle & Ovulation Pro is powered by the OvuSenseTM technology \u2013 a fertility tracking platform with 15 years of clinical research and trusted by physicians.<\/p>\n\n\n\n

        \n
      • The original OvuSense\u2122 product is a Class II medical device, cleared by the U.S. FDA (510(k) K122337) for intravaginal temperature-based ovulation tracking.5<\/sup><\/li>\n\n\n\n
      • OvuSense\u2122is also certified as a CE Class IIa medical device in the UK, European Union, Canada, and Australia, meeting all local stringent safety and performance standards.<\/li>\n\n\n\n
      • Cycle & Ovulation Pro adapts the OvuSense\u2122 algorithm for non-invasive, skin-based temperature sensing via the Ultrahuman Ring AIR \u2014 intended for general wellness and personal cycle awareness, not for diagnosis, treatment, or contraception.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
