Why we built Auromone
Cortisol shapes how you wake up, how you handle stress, how you sleep, and how your body stores energy. It's arguably the most influential hormone in daily life. Yet it has also been one of the least visible: measuring it has meant a blood draw, a saliva kit mailed to a lab, or a 24-hour urine collection, each a single snapshot of something that changes all day.
Meanwhile every popular wearable estimates "stress" from heart rate, which is a useful signal but not the hormone itself. We thought the most consequential hormone in your body deserved better than a once-a-year number or a proxy. So we set out to make it continuous, on-wrist, and yours.
The science: how the Curve reads cortisol
The Auromone Curve carries a small sensor on the underside of the band. A thin layer is shaped to lock onto cortisol; when cortisol in your sweat attaches to it, the sensor turns that into a tiny electrical signal, and a second electrode alongside it cleans up the background noise. The result is a reading of the active cortisol your body actually responds to, taken about 720 times a day.
In bench testing, the Curve tracked a lab blood test to within about 8% over 14 days of continuous wear, the same accuracy bar the continuous glucose monitors that people with diabetes rely on clear. We publish how the measurement works rather than treating it as a black box.
Built on decades of research
Cortisol isn't new science. The study of stress hormones traces back to Hans Selye, who gave "stress" its modern medical meaning in 1936, and the daily cortisol rhythm has been mapped for generations. What's new is the sensing: years of work on aptamer-style biosensors finally made it possible to read a hormone this small from sweat, on a device you can wear all day. Auromone sits at that intersection, turning lab-grade chemistry into something that fits on a wrist.
Honest about what it is
We say this plainly everywhere on the site: the Auromone Curve is a general wellness device under Health Canada and FDA guidance. It monitors continuously; it does not diagnose, treat, or cure any condition, and it is not a replacement for medical testing. We are pursuing Class II registration as our clinical data matures. If something in your data looks off, the right next step is a conversation with a healthcare provider.
Your data is yours. It's encrypted, exportable, owned by you, and never sold. Reservation details are stored in Canada. You can read exactly what we collect and why in our privacy policy.
The roadmap
Cortisol is first because it's the most universally useful. The same band is designed to take new sensor modules over time:
- Cortisol ships Q4 2026.
- Testosterone, estradiol, and melatonin modules are planned through 2028, on the same band with a fresh sensor.
Where we are
Auromone is based in Québec, Canada. The first 500 founder units ship in Q4 2026. Reserving is free, there's no deposit, and we only charge when your Curve ships. Questions, press, or partnerships: hello@auromone.com.
