Stress Level Tracker for Watch

The Stress Level app shows how your body responds to everyday life. It measures on your Apple Watch and keeps your history on your iPhone. The app combines heart rate and heart rate variability (HRV) to estimate your stress on a 0–100 scale, color-coded from low to high. It accounts for movement, workouts, and sleep, so physical activity isn't mistaken for stress. Key features: • Tracks stress all day in the background on your Watch, even without your iPhone nearby • Reads data securely from Apple Health, and your health data stays on your devices • 0–100 stress scale with clear colors: low, medium, high • On-demand check: one tap on your wrist for a fresh reading • Charts for today and yesterday on your Watch • A week of stress history on your iPhone, with daily averages Whether you're curious about stress or just like learning more about your body, the Stress Level app makes it simple. Disclaimer: The Stress Level app is not a medical device. Results are estimates intended for wellness and self-awareness only. The app performs best when used with a single Apple Watch worn consistently throughout the day.
