Hormone Lab

A redesigned app experience that turns your cortisol data into personalized, actionable insights — from daily actions to tag trends and notable moments.

Cortisol isn't a fixed number—it's a rhythm that naturally fluctuates, falling gradually from morning to night. When you get an unexpected reading, it's important to consider the context around it, since factors like timing, recent stress, sleep, and collection technique all impact your results. 

The new Testing Challenges feature provides six structured testing protocols—from establishing your cortisol baseline to assessing workout recovery and specific stressors—to turn your Hormometer™ data points into actionable insights for optimizing your daily routine.

Your master stress hormone controls energy, sleep, and recovery—when the rhythm breaks, everything feels harder.

Your score (0-100) is a daily pattern metric that shows how well your entire cortisol rhythm aligns with a healthy, optimal pattern for your time of day.

The 30-minute window before testing—no food, drinks (except water), brushing teeth, or smoking—ensures clean saliva and captures your complete cortisol response for accurate, reliable results.

Real-time hormone insights in 3 simple steps: saturate the pad for 60 seconds, pull until the blue dot shows, and wait 20 minutes for your results

Your diurnal curve is your complete daily cortisol rhythm—a powerful pattern that governs your energy, sleep, and stress response.

The right timing unlocks insight, as testing strategically is essential to understanding what shapes your personal cortisol pattern.

Most test issues are simple fixes—follow the ritual, saturate fully, pull until the blue dot shows, and your tests will work consistently.

Health tags transform raw biological data into meaningful, actionable personal insights by capturing the context and lifestyle factors surrounding each measurement.

Your evening cortisol is an extremely strong signal of sleep quality. Under 1 ng/mL = biochemically ready for sleep. Above 2 ng/mL = fighting your biology. Fix your evening cortisol, fix your sleep.
