Clair Health, a U.S.-based startup founded by Stanford engineering graduates, has introduced what it describes as the first bracelet designed to monitor changes in female hormone levels. According to Forbes, the company has raised $11.6 million (around R$60 million) in funding. More than 25,000 people have also signed up for its waitlist ahead of the official launch planned for November this year.
According to Clair Health, the wristband monitors more than 130 physiological biomarkers affected by hormonal changes, including body temperature and heart rate. It then uses machine-learning algorithms to interpret these combined signals and generate continuous hormonal data.
Hormone Levels and Health Metrics Tracked in Real Time
The technology can detect changes in estrogen, progesterone, LH (luteinizing hormone), and FSH (follicle-stimulating hormone) levels. It also monitors sleep, recovery, daily activity, and performance indicators. The device continuously monitors physiological signals in real time, making it suitable for women with irregular menstrual cycles.
The first software version of the wristband, called Clair 1.0, will initially be marketed as a general wellness product, a category that does not require approval from the U.S. Food and Drug Administration (FDA).
However, Clair Health says the device has been “validated against FDA-cleared at-home hormone tests” for continuous hormone estimation and menstrual-cycle phase classification.
The company also reports that its research was presented at the U.S. Department of Health and Human Services (HHS) National Conference on Women’s Health and is currently undergoing peer review. In addition, Clair Health is launching an independent clinical trial through the Stanford Gladstone BeeHive Initiative to further validate its commercial hardware.
Clair Health is also developing Clair 2.0 and plans to submit it to the FDA for approval, which could allow the device to make medical claims, including reporting quantitative hormone levels.
Clair 1.0 Devices to Receive Free Upgrade to Version 2.0
According to the startup, both versions will use the same hardware. Once regulators approve it, Clair Health will remotely upgrade all Clair 1.0 devices to Clair 2.0 at no extra cost.
Clair Health will sell the wristband for $369, which includes the device and six months of the Clair Pro subscription. After that period, the plan will cost $9.99 per month (approximately R$52).
Clair Health plans to ship pre-orders to the United States in December 2026, followed by the United Kingdom, Spain, Brazil, Australia, and New Zealand in January 2027. The company will begin shipping regular orders a few months later and continue deliveries throughout 2027.
Clair Health also warns that international customers may have to pay customs fees upon delivery. Before launch, the company says it will contact each customer to confirm their shipping address and delivery preferences.
