Home/The Curve band
A slim, matte band that reads the cortisol behind your energy, sleep, and stress, continuously, from the trace sweat on your wrist. No needles. No clinic.
One-time. The band is yours forever, and your first 4-pack of sensors is included.

An aptamer biosensor reads the cortisol molecule itself. Your ring only estimates stress from heart rate.
720 readings a day across sleep and stress, so you see the rise, the fall, and the recovery as they happen.
Cortisol today. The same band takes testosterone, estradiol, and melatonin modules through 2028.
founding members have already reserved their Curve. 320 spots remain.
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.
Picomolar resolution on the free, bioactive cortisol fraction, a matched control electrode to cancel drift, and everything else built to vanish on your wrist.
A single anodized shell flows into a soft, woven-feel band, with the Auromone mark quietly engraved into the top. 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 estimates stress from heart rate, a signal that barely tracks the real hormone. Here's what actually reads cortisol, and how.
| Reads the real hormone | How often | Where | |
|---|---|---|---|
| Auromone Curve | Yes | 720 a day, continuous | On your wrist |
| Whoop / Oura | No, a guess from heart rate | Continuous | On your wrist |
| Saliva / DUTCH kit | Yes | About 4 a day | Mail-in, days of waiting |
| Blood draw | Yes | One, that moment | A clinic, with a needle |

Whoop and Oura estimate cortisol from heart-rate variability, a signal that barely tracks the real hormone. Curve measures the cortisol molecule itself, from sweat. In bench testing it tracked a lab blood draw within about 8% over 14 days of continuous wear, the same accuracy bar continuous glucose monitors clear.
Yes. The band is permanent, but the cortisol sensor is the consumable that does the reading and lasts 14 days. Your first 4-pack is included; after that, refills are CA$29 per 4-pack. Shop sensors →
