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.

Ein Stern dafür dass die Messwerte zu stimmen scheinen. Die restlichen Sterne gibt’s, wenn es eine Anleitung für die App gibt. Vieles ist leider nicht selbsterklärend. Der Sound ist so extrem leise, dass man die Kopfhörer voll aufdrehen muss. Für Menschen welche schlecht hören leider nicht brauchbar. Schade, wo doch der erste Eindruck gar nicht mal so schlecht ist. ## Frequently asked questions about HRV Dojo ### What is HRV Dojo?
