Hot Flashes? There’s Now a Wearable for That
IdentifyHer’s new AI-powered wearable, Peri, tracks and decodes perimenopause symptoms, turning hormonal chaos into actionable data
One of the top gift ideas for older Millennial and Gen X women this year may just be a new wearable, one that doesn’t count steps or calories, but hot flashes and night sweats.
Behind it is IdentifyHer, a women’s health company that has launched Peri, a wearable designed to detect and decode symptoms of perimenopause.
The $449 device, which is HSA/FSA eligible and a 2025 CES Innovation Awards Honoree in Digital Health, is now available for pre-order, with deliveries starting in December.
“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,” IdentifyHer co-founder and CEO Heidi Davis said. “Women deserve real data, validation and support during this profoundly overlooked stage of life.”
The goal of Peri isn’t just to track perimenopause, but to help women understand it. The wearable uses biosensing tech and AI to gather symptom, activity and lifestyle data (tracking everything from hot flashes, night sweats, anxiety and sleep patterns) to daily routines, menstrual cycles, dietary habits and medications, then turns it into actionable insights.
Instead of relying on memory or self-reporting, Peri tracks physiological changes and looks for connections between them. Over time, the app surfaces weekly, monthly and cyclical summaries showing how symptoms shift and which habits may influence them.
The device is worn just under the breast, where IdentifyHer says it captures the most accurate data. Peri is rechargeable and can be worn for seven to ten consecutive days with a special adhesive. A chatbot is available to answer questions.
“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,” Davis said.
Other wearable leaders have also been pushing into women’s health tech.
Earlier this year, Oura rolled out new Pregnancy Insights and its first Perimenopause Check-In, expanding beyond fitness and recovery into reproductive and midlife health. The smart ring maker now helps users track gestational trends and symptom severity through features like the Menopause Rating Scale and partnerships with platforms such as Evernow, Maven and Midi Health.
Meanwhile, Ultrahuman has partnered with Clue, a women-led cycle-tracking app, to link biomarker data from its Ring Air with cycle insights for a more integrated picture of women’s health.
