Home/The Curve band
The Auromone Curve is a continuous cortisol monitoring device: a slim, matte band that reads the cortisol behind your energy, sleep, and stress from the trace sweat on your wrist. No needles. No clinic.
One-time. The band is yours forever, and your first month of sensors is included.

Everything a continuous hormone reading needs, in a band you forget you're wearing.
A small sensor reads cortisol itself. Your ring only guesses at stress from your heart rate.
Continuous readings across sleep and stress, so you see the rise, the fall, and the recovery as they happen.
Cortisol today. The same band takes new sensor modules as they arrive.

We built Curve so the most consequential hormone in your body stops being a number you glimpse once a year.Auromone · founding principle
The top shell is the brain you keep: battery, radio, and the chip that reads the sensor. A slim bottom tray snaps on with magnets and holds the sensor against your skin.
It reads even the tiny amounts of active cortisol your body responds to, with a second electrode alongside it to cancel background noise, and everything else built to vanish on your wrist.
A single anodized shell flows into a soft, woven-feel band. No screens, no buttons, no glow, just a calm object you stop noticing by day two.
The band reads; the app shows. Scrub back through any moment of your last 24 hours, see today against your own baseline, and watch the rhythm build across weeks. On iPhone and Android.
Your ring guesses at stress from your heart rate, a signal that barely tracks the real hormone. Here's what actually reads cortisol, and how the Curve compares as a cortisol tracker. For the full picture, see the best cortisol wearables compared.
| Reads the real hormone | How often | Where | |
|---|---|---|---|
| Auromone Curve | Yes | Continuous | On your wrist |
| A fitness band or smart ring | No, a guess from heart rate | Continuous | On your wrist |
| A saliva or dried-urine kit | Yes | About 4 a day | Mail-in, days of waiting |
| Blood draw | Yes | One, that moment | A clinic, with a needle |

A band or ring estimates stress from your heart rate, a signal that barely tracks the real hormone. Curve reads the actual cortisol, from sweat, continuously through the day rather than at a single moment.
