Cortisol: your body’s master stress signal

Hormometer™ turns the stress you feel into cortisol patterns you can actually see, track and change.


A healthy cortisol curve should peak in the morning and taper at night— but when that rhythm is disrupted, everything from energy to sleep suffers.

Cortisol reflects how stress shows up in your life

Mental and emotional stressors

Work pressure • Relationship strain • Life transitions

Physical stressors

Exercise • Illness • Overtraining + under recovery

Lifestyle stressors

Poor sleep • Caffeine + stimulants • Irregular routines

Environmental stressors

Frequent travel • Light exposure • Seasonal changes

Thousands have tried Eli. Here's what they're saying.

“I didn’t just want to know the what, I wanted to know the why.”

Emily

“The advantage of this [Eli's] type of test is that it doesn't require another party and can turn around results more quickly.”

“I didn’t just want to know the what, I wanted to know the why.”

Emily

“This is a game-changer, cortisol is the most illusive hormone. A reliable home kit is a 
life-saver for anyone struggling.”

Roman

"I loved seeing the real time impacts of my lifestyle habits, and that inspired me to make some changes to hopefully get my evening cortisol levels more balanced."

“I finally understand how my body responds to stress throughout the day. I can see patterns I never had access to before.”

Maya

“I finally understand how my body responds to stress throughout the day. I can see patterns I never had access to before.”

Maya

“They [cortisol tests] have been a good tool to learn about my habits and demystify the buzzy hormone. If you’re a fan of data and using tech in your wellness routine, Eli Health might also be for you.”

“When people actually see the data, it's clear feedback that enables them to prioritize different actions.”

"When used consistently, Dr. Jennifer Wagner, Chief Health and Performance Officer at Canyon Ranch, loves that it helps connect the dots between sleep, training load, and daily stress, turning a vaguely “stressed out” feeling into usable data."
