A new wearable device designed for women in perimenopause is now available in the U.S., entering the growing $80 billion global wearable technology market. IdentifyHer, an AI-powered women’s health company, launched Peri, a small device that tracks key perimenopause symptoms.
The palm-sized device sticks to the upper abdomen and monitors hot flashes, night sweats, anxiety, sleep patterns, menstrual cycles, and activity levels. Peri became available for order this week and was recognized as a CES Innovation Award honoree.
Heidi Davis, a molecular and cellular biologist and the CEO and cofounder of IdentifyHer—now rebranded as Peri—told Flow Space at the launch event in New York: “We want to give women the information they deserve so they can make informed healthcare decisions as they enter perimenopause.”
Perimenopause typically begins in a woman’s mid-40s, but it can start as early as the 30s. Common symptoms include hot flashes, night sweats, decreased libido, and anxiety. Davis said, “What we have found is that data validating these symptoms is very powerful and empowering. Women deserve information that confirms what they’re experiencing. We’re tired of being told it’s all in our heads.”
Unlike most health-tracking wearables, which are wrist bracelets or rings, Peri adheres to the upper body. Davis explained that research showed many perimenopause symptoms begin in the torso before spreading to the limbs. Heart rate and heart rate variability are tracked, and the device was tested on more than 100 women to refine its sensors.
To track anxiety, researchers conducted trials where women completed clinically validated anxiety questionnaires while wearing Peri. These results helped the team link psychological patterns to biosensor data.
The device pairs with an AI-powered app that offers weekly, monthly, and cyclical insights, helping women manage their symptoms effectively. Peri can stay on for seven to 10 days and uses two interchangeable batteries.
Davis added, “When women receive accurate health information, they make better decisions.”
Peri joins a growing trend in women’s health technology that focuses on hormonal health beyond reproductive years. Last month, Natural Cycles launched the NC° Band, a wearable that collects biometric data overnight to predict perimenopause stages.
“If symptoms are ignored, the risk of disease increases. We shouldn’t have to suffer for years before serious health problems appear,” Davis said. “Women deserve better than that.”
