Cortisol+ Stress Monitor & HRV

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. Glance at your wrist or a widget 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.
