IdentifyHer, an AI-driven women’s health company, has unveiled Peri, the world’s first wearable designed to detect and decode the symptoms of perimenopause. The innovative device, recognised as a 2025 CES Innovation Awards Honoree in Digital Health, is now available for pre-order in the U.S. ahead of its December release.
Peri aims to bring clarity to a life stage that affects more than one billion women worldwide, offering data-driven insights to help manage the often confusing and under-recognised symptoms of perimenopause.
“75% of perimenopausal women experience life-disrupting symptoms, yet perimenopause is treated like a mystery or an inevitability that women simply have to ‘power through.’ We reject this. Women deserve real data, validation, and support during this profoundly overlooked stage of life,” said Heidi Davis, BSc, MSc, CEO and Co-Founder of IdentifyHer. “With Peri, we are pioneering a new era of women’s healthcare; one where women are in control of their health and equipped to manage the symptoms that shape how we feel – physically, mentally and emotionally.”
Typically beginning in a woman’s early to mid-40s, perimenopause brings a wide range of symptoms including anxiety, sleep disruption, and hot flashes – many of which are often dismissed or misunderstood by clinicians. Peri’s proprietary biosensing technology and AI-powered analytics work together to track physiological signals and decode symptom patterns, providing users with personalised, actionable insights.
The discreet device also profiles symptoms across the menstrual cycle, mapping their interrelationships and tracking how they evolve over time. By giving users a clear understanding of what they’re experiencing, Peri enables more informed choices about lifestyle adjustments, clinical interventions, and overall symptom management. Users retain full control over how their health data is shared and used.
“Heidi and I first launched IdentifyHer with the mission to support women’s long-term health, and immediately recognised that to do this, we need to address the gap in perimenopause symptom data,” said Donal O’Gorman, PhD, COO and Co-Founder of IdentifyHer. “Our goal with Peri is to demystify perimenopause, but more importantly, to empower and reassure women they are not alone in what they’re feeling and it is possible to take proactive action towards their health.”
Perimenopause remains one of the least understood health stages for women, with research showing that 70% of women who seek medical help for symptoms receive no treatment, often due to inadequate diagnostics or a lack of clinician training. Furthermore, 84% report not being believed when describing their experiences.
Until now, managing perimenopause has largely depended on self-reporting, a method often inconsistent and difficult to track. Peri is the first device specifically designed to detect and interpret patterns unique to perimenopause automatically.
