Cortisol+ Stress & HRV Monitor

Cortisol+ helps you understand daily stress and recovery patterns by bringing together HRV, resting heart rate, sleep, activity and other Apple Health readings. Explore personal trends, wellness score contributors, sleep details and monthly activity recaps on iPhone and Apple Watch.

Use Apple Watch companions, seven complications and six iPhone widgets to view insights at a glance. Cortisol+ also includes guided breathing and meditation experiences, plus optional Fitbit and Oura connections. The app is designed for general wellness, does not measure cortisol levels, and is not a medical device.
