Sympathetic

Build a breathing practice and explore your heart’s response with Sympathetic. Follow visual, sound and haptic breathing cues. Connect a Polar H10 chest strap to view heart rate, heart rate variability (HRV) and ECG recordings. Review your sessions and explore how your measurements change during paced breathing. • Adjust your breathing pace and cues. • Compare breathing rates with a guided assessment. • Review session charts and recording history. • Export recordings for your own analysis. • Optionally save confirmed breathing time to Apple Health as Mindful Minutes. A Polar H10 chest strap is required for sensor measurements and is sold separately. Sympathetic is for personal exploration and general wellness. Its scores and ECG estimates are not intended for diagnosis or treatment.
