Resonance: HRV Biofeedback

Now available in Portuguese and Russian. A fairer resonance assessment: • Scoring no longer leans toward slow paces. Your ideal pace may change, so it's worth retaking the assessment. • A short warm-up, then the same number of breaths at every pace. Each pace is scored only on its own breaths. • Your ideal pace is now the pace with the biggest heart-rate wave within your coherent range. • Pro: see your range in seconds of inhale, coherence and wave size for each pace side by side, and when to choose the faster end. More accurate with chest straps like the Polar H10: • Every heartbeat is now recorded. Beats that arrived together were sometimes dropped. • Beat timing follows the strap's own clock, for a cleaner heart-rate wave. • HRV (RMSSD) no longer reads high from estimated beats mixed in with real ones. • Beat data is kept for the whole session, not just the last two minutes. • New assessment tip: a chest strap gives the most accurate result. • The analysis report now shows total practice time. • Box breathing and other exercises with holds: a soft tick and a gentle vibration (if enabled) now mark the start of each hold. • Tap your ideal pace card to see your assessment summary again.
