While smartwatches primarily focus on monitoring cardiovascular health, Clair aims to provide in-depth insight into hormone levels and monitor them around the clock to provide valuable information about athletic performance, fertility, and a woman’s menstrual cycle.
Smartwatches, such as the Samsung Galaxy Watch7, can monitor several health metrics using a heart rate sensor, blood oxygen saturation (SpO2), electrocardiogram (ECG), and skin temperature sensor. However, Clair Health sees a gap in this area, as smartwatches do not monitor hormone levels.
Here comes the role of the company’s new bracelet; According to the manufacturer, the wearable device can detect estrogen, progesterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH), and determine how hormone levels change throughout the day. This would allow, among other things, a more accurate prediction of the menstrual cycle, especially when compared to a smart watch that usually relies only on data from the skin temperature sensor.

The accompanying smartphone app is designed to calculate the exact fertility window based on hormone data. Furthermore, estrogen levels are intended to provide valuable insights into athletic performance, helping users determine the optimal time for an intense workout. Clair Health mainly targets female athletes, women going through menopause, and those wishing to become pregnant.
Clair Health has not yet provided details on exactly how it measures hormone levels, so interested buyers are advised to wait for independent tests or studies to prove the accuracy of the data Clair collects.
Price and availability Clair Health has not yet confirmed when the hormone tracking bracelet will be released or at what price. However, people who register their email addresses on the manufacturer’s website will receive a 50% discount on the device at launch, as well as free lifetime access to the companion smartphone app.
