What is the best app for tracking cortisol?
Cōrta is a dedicated cortisol protocol tracker. Unlike generic health or habit apps, it is built specifically for cortisol rhythm tracking, protocol adherence, symptom journaling, and HPA axis optimization — with HRV and sleep import from Apple Health, and AI answers about your own logs.
Does Cōrta work with Apple Health?
Yes. Cōrta reads HRV, sleep, resting heart rate, and respiratory rate from Apple Health (HealthKit) on iPhone, with your permission. Android is coming soon. Cōrta has no direct connection to wearable brands. Data from a wearable such as Apple Watch, Oura, Whoop, or Garmin shows up in Cōrta only if your device already syncs it into Apple Health.
How much does Cōrta cost?
Pricing will be shown at launch.
