About This Product.

Clair is a wrist-worn wellness wearable developed by women's health startup Clair Health, founded by Stanford graduates Jenny Duan and Abhinav Agarwal. It is designed to be the first device of its kind to offer continuous hormone monitoring for women in a non-invasive format.

Rather than requiring blood draws, urine tests, or finger-prick samples, Clair works through physiological inference — using an array of 10 biosensors to read signals from the body and generate real-time estimates of hormone patterns, including oestrogen and progesterone. The sensors monitor a range of physiological data points: skin temperature, heart rate, heart rate variability (HRV), respiratory rate, electrodermal activity, and sleep data. Onboard AI interprets these signals across more than 500 biomarkers to produce hormone insights.

For women navigating training load, cycle-based periodisation, or simply wanting a clearer picture of their hormonal health across the month, that kind of continuous visibility — delivered passively, without clinical appointments — represents a meaningful shift in what self-monitoring can look like day to day.

Beyond hormone tracking, Clair functions as a full-stack wellness wearable, capturing sleep quality, recovery, daily activity, and performance metrics alongside hormonal data. Everything is surfaced through an accompanying app, turning hormonal self-knowledge into a routine, accessible practice rather than a clinical undertaking.

Clair is expected to be available from November 2026. It is designed specifically for women, with the aim of making hormonal health monitoring as straightforward as wearing a watch.

Finally, something built with women's physiology in mind

4 months ago

I've been using this for about three weeks now and it's genuinely changed how I approach my training week. I do a lot of cycling and I'd been trying to manually track my cycle alongside my training load — spreadsheets, apps, the works. Having it all in one place on my wrist, passively, without having to do anything extra, is brilliant. The hormone pattern data took a few days to feel meaningful but once it clicked I started noticing real correlations with my energy levels and recovery scores. The app is clean and not overwhelming. Really glad I pre-ordered when I did.

Impressed by how unobtrusive it is

Wears like a normal watch, which I appreciated — I'd been put off by bulkier fitness trackers before. The sleep and HRV data alone would be worth it for me, but the hormone layer on top makes it feel like something genuinely different. Early days still but I'm noticing patterns I hadn't before.

Really promising, but the app needs polish

6 months ago

The hardware itself is lovely — light, comfortable, doesn't snag on sleeves. The hormone tracking is fascinating and I've already started using the cycle data to plan my heavier training days around my oestrogen peaks, which feels like a sensible thing to do. My only real frustration is with the app: the notification settings are clunky and I keep getting duplicate alerts that I can't seem to switch off individually. It's clearly still being refined. At £369 I'd expect the software side to be a bit tighter. That said, I'd still recommend it — just go in aware that it's not fully polished yet.

Bought this after a friend who trains for triathlons wouldn't stop talking about it. Took about a week to trust the data but now I check it every morning alongside my sleep score. Feels like proper self-knowledge rather than just step counts.
