Resonate: Heart Coherence

Bring your breath, heart rhythm, and nervous system into sync. Real-time coherence feedback on iPhone and Apple Watch.

Resonate is a heart-coherence trainer for iPhone and Apple Watch. It gently guides your breathing to help bring your heart rhythm and nervous system into a smooth, balanced state known as coherence.

Breathing is simply the mechanism — coherence is the goal. As your heart rhythm becomes smoother, the experience responds in real time: the haptics soften into a living pulse, the audio grows richer, and the central visual becomes more symmetrical and luminous. Resonate is a mirror of your state, not a metronome.

FEATURES • Real-time coherence score from your live heart rate and heart-rate variability (Apple Watch + HealthKit) • Multiple guided breathing exercises, each with its own resonant frequency and visual • Gentle, breath-synced haptics that weave in your own heartbeat • Apple Watch app with synced breathing and session stats • "Breathe Together" — sync a session with people nearby over Bluetooth/Wi-Fi • Optional calming tones tuned for headphones and AirPods

For the best experience, use a paired Apple Watch and headphones.
