- It is the first perimenopause wearable device of its kind.
- Peri tracks perimenopausal symptoms.
- One of the first wearable devices designed for perimenopausal tracking.
Health wearables started as step counters and sleep trackers. Now the industry is focused on helping people through an often overlooked biological period: perimenopause.

Peri, one of the first wearable devices designed to monitor perimenopausal symptoms, is showcased at CES 2026. Unlike typical health wearable devices, the $449 device, which Now available for preorderPrimarily designed for those experiencing perimenopause, the transitional period before menopause that typically lasts between three to 12 years.
non-intrusive device
The device looks similar to a continuous glucose monitor (although Perry’s sensor is not intrusive, it is attached near the abdomen, and there is no needle involved). According to Perry’s website, it tracks perimenopause signs and captures data like body temperature, sleep, and cycle information. At CES, I noticed that the Peri is about the same size as your typical CGM – if not slightly larger – and less flexible in construction.
The device is packed with four sensors: a PPG for blood flow, an accelerometer for motion, an EDA for measuring skin electricity, and a temperature sensor. These sensors, paired with Perry’s custom algorithms, can detect and monitor perimenopausal symptoms such as hot flashes, night sweats, anxiety and changes in sleep patterns.
Plus: This device may help make periods more comfortable
“Perimenopause is treated like a mystery or an inevitability that women just have to ‘power through.’ We reject that. Women deserve real data, validation, and support during this highly neglected stage of life,” Heidi Davis, CEO and co-founder of IdentifyHer, the company behind Perry, said in a press release.
Biomarker records
Users attach the device under their breast, where it records biomarkers for about seven to 10 days before needing a recharge. Perry says it aims to address common perimenopausal challenges like hot flashes, sleep disruption, night sweats, and more through its biosensors and AI-powered analytics. Their custom algorithm doesn’t just detect hot flashes caused by changes in temperature, but it is using a mix of data metrics to accurately predict and record these symptoms.

Symptoms are logged in the context of the user’s menstrual cycle so that their connection can be examined and changes can be tracked over time. They can also document hormone therapy treatment visits and see how their treatment is affecting other aspects of their perimenopausal experience.
On the home page, users can view their sleep time, anxiety score, activity level, and cycle information. There’s also a journal feature to record mood, as well as a tab for daily, weekly and longitudinal insights.
The device was first born out of a gap in perimenopause symptom data. In a press release, IdentifiHer’s founders say that poor diagnostics and a lack of physician training leave people experiencing this period disadvantaged in their condition.

“Until now, management of perimenopause has relied on self-reporting, an approach that can be inconsistent, subjective, and difficult to track over time,” said Donal O’Gorman, COO and co-founder of IdentifyHer.
CES Honored
The device was a 2025 CES Innovation Award honoree in digital health. Following November pre-orders, Perry is set to launch in December.
