Offline neurological wellness, tremor tracking & cognitive latency assessment.
NeuroPulse is an offline neurological wellness tracking platform. Powered by mobile sensors and advanced signal processing algorithms, NeuroPulse quantifies physiological tremor cadence, executive cognitive latency, and motor coordination—with zero internet connectivity and zero cloud telemetry. All biomarker calculations, Fast Fourier Transform (FFT) spectral analyses, and encrypted PDF generations occur 100% on-device, protected by hardware-backed Android KeyStore encryption. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY CAPABILITIES & PROTOCOLS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔬 1. KINEMATIC TREMOR LABORATORY • Gyro Horizon Reticle: Dynamic artificial horizon ensures standardized postural alignment. • 100 Hz Sampling: Captures subtle micro-oscillations via hardware sensors. • 4–8 Hz Biquad Filter: Isolates physiological resting and postural tremor frequencies. • Radix-2 FFT: Computes real-time Power Spectral Density (PSD) over a 512-sample Hanning window to calculate peak frequency (Hz) and steadiness index. 🧠 2. EXECUTIVE COGNITIVE & LATENCY AUDITS • Stroop Conflict Audit: Measures prefrontal attentional control and executive interference via randomized color-word conflicts with microsecond touch dispatch. • Psychomotor Vigilance Task (PVT): Measures sustained attention, sub-millisecond reaction delay, and detects attentional lapses (>500ms). • Finger Tapping Cadence: Evaluates motor rhythm velocity, inter-tap intervals, and rhythm variability. 📊 3. NEUROPULSE STABILITY INDEX • Composite Score: Normalizes rolling 30-day baseline deviations (Z-scores) across kinematic stability and cognitive processing speed into an intuitive 1–100 wellness index. • Longitudinal Archive: Track 30-day baseline statistics and dispersion metrics (mean μ, standard deviation σ) in an encrypted vault. 📑 4. AIR-GAPPED VECTOR PDF DOSSIER • On-Device Vector PDF: Generates multi-page A4 summaries directly on your device without cloud servers. • Includes stability score, tremor power spectrum curves, cognitive latency histograms, trendlines, and dispersion tables. • Secure SAF Export: Save to storage or share via local apps (Quick Share, printing) safely. 🛡️ 5. AIR-GAPPED PRIVACY & SECURITY • ZERO INTERNET PERMISSION: Declares no android.permission.INTERNET. Impossible for the app to transmit health data to any server. • KeyStore AES-256 GCM: Master encryption keys are sealed in hardware KeyStore. • SQLCipher Encrypted DB: All records are stored in a 256-bit encrypted Room database. • Biometric Vault: Unlock records using biometric authentication (fingerprint, face unlock) or device PIN. 🌐 6. GLOBAL ACCESSIBILITY & DESIGN • 9 Offline Languages: Localized in English, Spanish, French, German, Japanese, Chinese, Arabic, Bengali, and Hindi. • Adaptive Layouts: Responsive interface for phones, foldables, and tablets in portrait and landscape. • Medical Themes: Obsidian Dark, Clinical Light, and Midnight Blue palettes. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ IMPORTANT MEDICAL DISCLAIMER ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ NeuroPulse is designed exclusively for informational, educational, and personal neurological wellness tracking.
