The differences that matter
Auromone Curve vs Oura & Whoop
The Oura Ring and Whoop are great at what they do, but neither measures cortisol. Their stress scores are worked out from your heart rate, which reflects your nervous system, not the hormone that actually drives stress. Your heart rate barely tracks real cortisol. The Auromone Curve reads the actual cortisol from sweat, about 720 times a day, so you watch it climb and come back down as it happens instead of reading a made-up "stress" number.
Auromone Curve vs saliva tests (ELI Health, DUTCH)
Saliva tests do measure real cortisol, but only in the few moments you collect a sample, and usually after a wait for the lab. Cortisol is a pattern, not a single point. A level that looks fine at 8 AM can be off by 10 PM. The Curve reads all day on your wrist, so it captures the whole day's pattern. No spitting into a tube on a timer, nothing to mail in.

Auromone Curve vs a blood test
A blood test is the gold standard for a single moment, and it is still the right tool for a diagnosis. But it is one number, from one needle, at one time. The Curve does not replace a clinical test. It gives you an all-day view between those moments. In our bench testing it stayed within about 8% of a lab blood test, about as close as the glucose monitors people with diabetes trust.
Like a glucose monitor, but for cortisol
Glucose monitors turned the occasional finger-prick into a live view of blood sugar. The Auromone Curve does the same for cortisol. It turns the rare lab snapshot into an all-day read, on your wrist, of the hormone behind your energy, sleep, and stress.
