## What is ZenBreath?

The breathing instrument you feel, not watch.

ZenBreath AI is not another content-heavy meditation library with 40-minute audio monologues. It is a precision physiological instrument engineered for your autonomic nervous system.

Continuous haptic waveforms guide every stage of your breath — a gradual physical swell as your diaphragm descends, a subtle heartbeat pulse at peak capacity, and a smooth, dissolving release as you exhale. Close your eyes and feel the full physiological arc of your breath through your fingertips.

CLINICAL & EVIDENCE-INFORMED PROTOCOLS
• Tactical Box Breathing (4-4-4-4): Balance autonomic arousal during high-stakes focus.
• Sleep Wind-Down (4-7-8 Weil Protocol): Extended exhalation to stimulate vagal brake and induce parasympathetic dominance.
• Pre-Meeting Reset (3-3-3-3): 30-second physiological sigh to rapidly steady tremor and tachycardia.
• Commute Peripheral Mode: Glanceable horizontal cadence bar designed for train and bus commutes without social awkwardness.
• Post-Lunch Revive: Rapid inhalation dominance to disperse postprandial lethargy.

ZERO-LATENCY AI RHYTHM GENERATION
Describe your context in natural language ("just got harsh feedback", "overcrowded subway commute"). On-device Foundation Models generate an anatomically calibrated rhythm immediately. No spinners. No server lag. Zero external data transmission.

HONEST, MOTION-GATED BIOFEEDBACK
Unlike apps that display distorted Heart Rate Variability (HRV) during physical motion, ZenBreath’s accelerometer gate detects transit and body vibrations. When motion is detected, questionable HRV metrics are automatically withheld to maintain physiological accuracy.

PRIVACY & ETHICAL BY DESIGN
• Zero account required. Open and practice in 0ms.
• 100% on-device local storage. No advertising SDKs, no behavioral trackers.
• Native Apple Health integration (Mindful Minutes).
• Designed for iPhone with full CoreHaptics continuous waveform acceleration.
