Calm Rhythm is a stress and sleep tracker that turns your Apple Health data into clear, actionable insights. • True stress index – estimated from HRV (heart rate variability) and heart rate, not just mood checkins. • Daily dashboard – see today’s stress level, HRV, heart rate, sleep and steps in one calm home view.  • Trends & scores – weekly and monthly stress, recovery, sleep and activity scores so you notice changes early. • Professional insights – simple explanations of HRV, cardiovascular health, sleep and recovery based on your data. • Smart reminders – optional notifications for morning sleep recap, afternoon move reminder and evening winddown. • Biological age (beta) – an estimate based on sleep, HRV, heart rate and activity patterns. Calm Rhythm reads data from Apple Health / HealthKit (HRV, heart rate, sleep, steps) and keeps processing on your device. It is designed for wellness and selfawareness only and does not provide medical diagnosis or treatment. Always consult a doctor for any medical concerns.
