StressBook: Watch HRV Tracker – Beherrschen Sie Ihren Stress, gewinnen Sie Ihre Vitalität zurück

StressBook uses Apple Watch health data—such as HRV (heart rate variability) and resting heart rate—to help you understand physical fatigue and psychological stress. It sends timely reminders to keep you mindful of your stress state and helps you learn to regulate and manage stress so your body and mind stay in a comfortable, balanced state. Through data analysis, it provides valuable insights to help you find inner calm and ease. ◎ What StressBook can help you do * Quickly view your current HRV-based stress level on your iPhone and Apple Watch * Explore detailed, comprehensive historical analyses to better understand your stress cycles * See real-time stress, vitality, and body energy levels * Review daily health indicators on the Insights page * Log water intake, with configurable drinks such as coffee, milk tea, and more * Relieve stress and anxiety with multiple breathing exercises and improve sleep onset * Do Kegel training * Measure accurate HRV in real time (this feature requires Apple Watch ECG support and is not available on all models or in all regions) * Tag stress records and add notes for easy review * Get wellness tips from wellness-focused watch faces ◎ Apple Health integration StressBook reads heart-related health data from your Apple Watch via Apple Health. StressBook requires read permissions from Apple Health to send reminders, track stress moments, and provide suggestions; otherwise, it cannot function properly. Rest assured, your health data is stored locally on your device—we do not upload any of your health data. ◎ Health advice disclaimer All information and suggestions provided by StressBook are not medical advice or a diagnosis and should not replace professional diagnosis or treatment. If you feel overly stressed and unable to cope, or before making any medical decisions, please seek help from a qualified healthcare professional promptly.
