------------Designed for Apple Watch Users Stress Self-Assessment Tailored for Apple Watch Users: It analyzes your heart data and displays your current psychological stress levels, as well as your mental, emotional, and physical states. With your watch, it's a great tool for stress self-assessment, monitoring, and recording, as well as detecting stress. ------------Measure Psychological Stress Anytime When wearing your Apple Watch, it automatically generates HRV (heart rate variability) data. The Stress Self-Assessment App analyzes HRV data, combined with resting heart rate, age, and other factors, to provide a comprehensive stress assessment level. This process requires no intervention, but you can also use mindfulness apps or ECG apps on your watch for quick psychological stress tests and monitoring, obtaining HRV values and psychological stress status. ------------Multi-Dimensional Full-Cycle Data We provide multi-dimensional, full-cycle psychological stress data charts, allowing you to intuitively understand changes in stress trends and psychological pressure over longer periods. This includes weekly, monthly, and yearly stress trend charts, stress frequency statistics, stress period statistics, stress scatter plots, and more. We offer comprehensive psychological stress data charts to help you clarify the root causes of stress, manage emotions, and improve mental health. ------------Intelligent Psychological Stress Reminders With stress reminders, you can timely perceive changes in your psychological stress status. When new HRV data is generated, the Stress Self-Assessment App automatically sends a notification to your watch or phone, reminding you to pay attention to your psychological stress status and maintain good physical health. ------------Automatic Health Check-Ins Leveraging powerful Apple Health integration, we combine seven health habits including steps, sleep duration, mindfulness duration, hydration, hand washing, standing time, and energy burn. This helps you easily understand these data points, promoting robust physical health and a pleasant inner state. ------------Privacy and Security We understand your personal health data is sensitive. Stress Self-Assessment only directly reads data on your device via the Apple HealthKit API, and all your data is stored locally. ------------------------------------------------------------ Advanced Membership Subscription Explanation: By becoming an advanced member of Stress Self-Assessment, you unlock all paid features, enjoy free updates for future advanced functionalities, and a commitment to ad-free service.
