About Resonance: Breath & Calm
Resonance trains you to steer your own inner state through breath. Not just another meditation app — a real path that builds, level by level, your ability to drop into calm at will, and to stay composed when the pressure rises. Two complementary sides: • DESCENT — bring the pressure down: resonance breathing (heart coherence), long exhales, the physiological sigh, body scan. • CONFRONTATION — widen your tolerance: CO₂ tables, breath-holds, dry apnea. 5 GUIDED PROGRAMS • First breaths — one gentle week to get started (free) • Resonance — the core 10-level path: descent and confrontation • Sleep better — an evening ritual that prepares the night • Mindfulness — a real meditation practice, step by step • Deep breath-hold — tables, holds, CO₂ tolerance THE ACTIVATION PROTOCOL A voice-guided morning ritual (5 or 10 min): settle in, wake the body, then direct your attention — gratitude, your best self, your intention. REAL BIOFEEDBACK Connect a chest strap (Polar H10…) and watch your heart sync with your breath, live. Coherence score, and a resonance test to find YOUR personal frequency — only your real data, no invented numbers. AND MORE • 11 meditations and self-hypnosis tracks, in 4 voices, English and French • Sessions keep running with the screen locked, music included • Free sessions, an express toolkit, measurements (BOLT, HRV, resting pulse) • Your own proof: records, curves, weekly volume • No account — your practice data stays on your phone RESONANCE PREMIUM 7-day free trial, then $69.99/year or $9.99/month. The First breaths program stays free. Safety first: dry-land training only, never in water or while driving. Resonance is not a medical device and does not replace professional advice.
