HRV Dojo: Biofeedback Trainer

HRV Dojo is a focused HRV biofeedback app for people who train better when they can see clean heart data in real time. Connect a compatible Bluetooth heart-rate sensor and HRV Dojo turns RR intervals into practical sessions for readiness, breathing, workouts, and recovery review. Use HRV Dojo to: - Watch live heart rate and RR interval quality - Measure HRV metrics including RMSSD, SDNN, pNN50, and lnRMSSD - Run a 3-minute readiness check and build a personal baseline - Practice guided breathing and resonance scans with coherence feedback - Track workouts with heart-rate zones and recovery metrics - Export CSV and backup data - Save completed workouts and heart-rate samples to Apple Health when allowed HRV Dojo is designed for compatible Bluetooth heart-rate sensors that provide RR interval data. Signal quality matters, so the app highlights artifact filtering and warns when a reading is not reliable enough for readiness work. This app is for wellness, training, and self-tracking. It is not intended for clinical decisions, emergency monitoring, diagnosis, treatment, or disease monitoring.
