StressWatch:HRV Stress Tracker is a free lifestyle app available for iPhone. Developed by 晟 徐, this app relies on your RHR (Resting Heart Rate) and HRV (Heart Rate Variability) data retrieved from Apple Health to determine your current stress levels. It constantly monitors your status and provides immediate reminders if your stress levels get too high, allowing you to take action to reduce your stress levels.

StressWatch offers several ways to help you manage your stress levels. Whether you're working late into the night, attending a social event, or have had too much to drink, the app provides gentle reminders based on your HRV data. You can also monitor your HRV levels and stress levels from your Apple Watch by adding StressWatch to your Watch Face. Additionally, the app allows you to analyze your weekly and monthly stress levels over prolonged periods of time, helping you track your progress.

The design concept of StressWatch focuses on delivering data in a friendly manner. The app introduces the "Stress Bubble," which changes colors as your stress levels rise. This visual representation helps users interpret their stress levels easily.

While the current version of StressWatch provides valuable features, the developers have plans to add more in the future. These include daily stress recovery assessments, ECG-based HRV measurements, additional Apple Watch Faces, and HRV and resting heart rate trending.

Please note that StressWatch requires read authorization from Apple Health to function properly. Your health data is stored locally and not uploaded.
