# RE: Balance Breath, Body, Mind

> RE is a privacy-first, bio-regulatory breathwork and Heart Rate Variability (HRV) biofeedback application. Built on first-principles neuroscience and autonomic physiology, RE helps users regulate their nervous system, build stress resilience, improve sleep quality, and enhance focus without gamification, ads, or AI sycophancy.

## Core Philosophy & Design Principles

- **First Principles Physiology**: Breath is the master switch of the human autonomic nervous system. RE optimizes this single mechanism (0.1 Hz resonant frequency breathing: 5.5 seconds in, 5.5 seconds out).
- **Client-Side Privacy First**: Zero data harvesting, zero ads, no cloud tracking. All biometric calculations remain strictly on-device.
- **No Gamification**: Free of streak pressure, artificial badges, or pushy notifications. Designed as a precise bio-regulatory instrument.
- **Camera PPG Scanner**: Clinical-grade photoplethysmography (PPG) using smartphone camera and flash—no smartwatch required.

## Key Features & Capabilities

- **Resonant Frequency Breathing**: 0.1 Hz pacing (4.5s to 6.5s per phase) aligning respiration with cardiovascular baroreflex sensitivity.
- **Biometric Metrics**: Tracks 7-day Balance (HRV), Vagal Recovery (RMSSD), Cardiac Coherence (Body, Breath, Heart), and Heart Rate (BPM).
- **Soundscapes & Cues**:
  - **Harmonic Chime**: Minimalist, non-binaural bell tone at respiratory pivot points.
  - **Binaural Beats**: Delta (3.2 Hz for sleep), Theta (5.0 Hz for meditation), Alpha (7.8 Hz Schumann resonance for focus).
  - **Audio Scapes**: Coloured noise (Brown, Pink, Green) for masking environmental distractions and quietening mental chatter.
- **Group Resonance Coherence**: Global 20-minute synchronized breathing circles starting on a fixed clock.

## Target Applications & Use Cases

- **ADHD & Neurodiversity**: Bottom-up somatic anchoring for overstimulated minds where silent meditation backfires.
- **Autonomic Regulation**: Vagus nerve stimulation, lowering sympathetic drive, restoring parasympathetic tone.
- **Post-Workout & Recovery**: Accelerating post-exercise HRV recovery and autonomic balance.
- **Sleep & Rest**: Deepening slow-wave sleep through Delta entrainment and vagal activation.
