Callahorn Resonance

Resonance is a calm space for focus, relaxation, meditation and sleep. Choose an intention, layer in soothing sounds, set a timer, and let the tones do the rest. BINAURAL BEATS Four presets — Focus, Relax, Meditate and Sleep — each tuned to a different brainwave band, plus a Binaural Frequency Tuner for dialing in any beat from 0.5 to 40 Hz. Warm, low carrier tones stay comfortable for long sessions. AMBIENT MIXER Blend rain, ocean, wind, fire and stream with musical pads — Warm Pad, Deep Drone and Shimmer — each with its own volume. GUIDED BREATHING Follow a gentle visual guide for Equal, Coherent, Relax, Box or 4-7-8 breathing. 8D SPATIAL AUDIO Let the ambience slowly orbit around your head for a deeply immersive listen. SLEEP TIMER Sessions from 5 to 60 minutes end with a soft fade and a gentle chime — even with the screen locked. PRIVATE BY DESIGN Every sound is generated on your device. Resonance works fully offline and collects no data — no accounts, no ads, no tracking. Best experienced with headphones. Resonance is intended for relaxation and general wellbeing. It is not a medical device and is not intended to diagnose, treat or cure any condition.
