Track your cortisol, sleep and recovery — and share your health with your closest circle. Now with a full fitness hub and richer sleep insights.
Your Apple Watch already senses your stress. Cortisol+ turns its heart rate, HRV, and sleep into a real-time cortisol score - so you can catch stress building and calm it before it peaks. No lab tests, no finger pricks. Just your watch and a clearer picture of your body.
WHAT'S INSIDE
- Live cortisol & stress score, read from your Apple Watch biometrics through the day
- Full sleep analysis - sleep stages, quality score, sleeping heart rate, and how each night shapes tomorrow's stress
- Pace of Aging & Bio Age - see how fast your body is really aging from your recovery data
- Vitals trends - HRV, resting heart rate, blood oxygen and more, each with your personal "in-range" benchmark
- Your Cortisol Range - what's normal for you, and what's driving today's number
- Zen, your AI coach - 2-minute breathwork and meditations for anxiety, focus, and deeper sleep
- Daily Breakdown - a plain-English recap of what moved your cortisol, powered by private on-device AI
WHY CORTISOL+
Chronically high cortisol quietly drives anxiety, poor sleep, burnout, and faster aging - and most people never see it happen. Cortisol+ makes it visible: it reads the signals your Apple Watch already collects (heart rate variability, resting heart rate, sleep and activity) and turns them into one clear score you can act on.
Check it in the morning to see how you recovered. Watch it through the day to spot what spikes you. Wind down at night with Zen. Small, consistent steps compound into calmer days and better sleep.
PRIVATE BY DESIGN
Your health data stays yours. Insights are generated on-device.
Works with Apple Watch. Start understanding your stress today.
Cortisol+ is not a medical device and does not diagnose, treat, or measure cortisol from blood. Estimates are for wellness and informational purposes only.

This app has everything I need for my fitness journey. I needed something to track my stress and cortisol levels. This tracks my Blood O2 levels, resting heart rate and HRV. Really cool. It also tracks my sleep and my activity. I connected with friends and we are sharing our progress with each other. This is actually cool.
