Frequently Asked Questions
Common questions about Stress App
What is Stress App?
Stress App is an Apple Watch stress monitoring app that helps you understand and manage your stress levels by tracking heart rate and heart rate variability (HRV) data.
How does it measure stress?
We analyze your heart rate variability (HRV) data to assess stress levels. HRV is the tiny variation in time between heartbeats and is an important indicator of autonomic nervous system activity.
Do I need an Apple Watch?
Yes, Stress App requires an Apple Watch to obtain heart rate and HRV data. We support Apple Watch Series 4 and later.
Which devices are supported?
Stress App supports all Apple Watches running watchOS 10 or later, and iPhones running iOS 17 or later.
Is my data secure? How is my privacy protected?
Your health data is stored entirely on your device and in your iCloud. We do not upload or store any of your health data.
What's the difference between Free and Pro?
The Free version provides basic stress monitoring features, including Today's HRV and Current HRV. Pro offers more advanced features like real-time stress monitoring, stress trends, historical data, sleep analysis, and more.
How do I understand stress levels?
Stress App levels are divided into four levels: Relaxed (0-34), Normal (35-54), Medium (55-79), High (80-100). Higher levels indicate more stress, suggesting you should take relaxation measures.
Does it affect battery life?
