🧘 Who (Audience & Creators)

Who is this for?

• The Busy Developer: You live in the terminal. You need a 5-minute reset without context-switching to a mobile app.
• The Everyday Human: You are taking a break or encountering a moment of stress. You need a simple, immediate tool to help you reground.
• The Daily Commuter: You need an offline-ready, privacy-first tool that works on 3G.
• The Biohacker: You want scientifically-rigorous 150Hz customization to sync with your HRV monitor.

Who made this? Maintained by Phil Gear and an open-source community dedicated to mental resilience.

🌿 What (The Ecosystem)

New in v3.1.0 "The Minimalist Edition": The Mindful Breathing Visualizer has been completely overhauled to follow the "Less, but better" design philosophy.

• Minimalist Aesthetic: A strict monochromatic palette with a single International Orange interaction accent. No gradients, no shadows, no distractions.
• Stereo Balance Indicator: A new high-fidelity UI for Alternate Nostril Breathing that mimics analog audio equipment.
• Pure Function: Emojis and decorative text stripped away. Information is conveyed through clear, geometric signals.
• Smart Durations: Context-aware defaults (Box=4s, 4-7-8=4s/7s/8s, Diaphragmatic=Relaxing).
• 150Hz Audio Sync: Real-time sine wave synthesis that rises/falls with breath.
• Scientific Rigor: Animations modeled on piece-wise respiratory sinus arrhythmia (RSA) functions.

🌌 The "Serene Palette" Across 39+ Dimensions

We have ported the exact same 150Hz sine-wave logic and "Serene Palette" design to every major stack to prove that mindfulness is universal.

🛡️ Why (Validated Science & Math)

Validated Science Our design constraints (5+ minute duration, guidance cues, slow pacing) are aligned with the framework established by Bentley et al. (2023) in their systematic review of 58 clinical studies.

Source: "Breathing Practices for Stress and Anxiety Reduction: Conceptual Framework of Implementation Guidelines." Brain Sci. 2023, 13, 1612. DOI: 10.3390/brainsci13121612

The Math We model the breath using piece-wise functions to ensure smooth transitions that mimic natural RSA: $$ f(t) = \begin{cases} 0.5 - 0.5 \cos(\frac{\pi t}{4}) & 0 \le t < 4 \quad (\text{Inhale}) \ 1 & 4 \le t < 8 \quad (\text{Hold}) \ 0.5 + 0.5 \cos(\frac{\pi (t-8)}{4}) & 8 \le t < 12 \quad (\text{Exhale}) \ 0 & 12 \le t < 16 \quad (\text{Hold}) \end{cases} $$
