Auralynx: Stress + Heart Rate

Auralynx — Voice & Motion Stress Insights

Ever wondered what your voice reveals about how you really feel? Auralynx uses your phone's microphone and motion sensors to measure subtle changes in your voice patterns and hand stability, giving you a real-time stress and confidence indicator. No uploads, no accounts, no cloud — everything runs 100% on your device.

Whether you're exploring self-awareness, playing a party game with friends, or simply curious about how your body reacts under pressure, Auralynx turns your phone into a personal biometric companion.

HOW IT WORKS

Calibrate — Speak naturally for about 8 seconds to establish your relaxed voice baseline (pitch, energy, and micro-tremor patterns).

Answer — Respond to questions for 8 seconds each. Auralynx compares your answers against your personal baseline in real time.

Review — Get an instant stress score (0–100) with a clear grade: Calm and Collected, Mostly Relaxed, Slightly Nervous, Stressed, or Highly Stressed. See exactly how much pitch, energy, and tremor contributed to your score.

KEY FEATURES

◆ Voice Stress Analysis
Advanced on-device signal processing detects shifts in pitch, vocal energy, zero-crossing rate, and hand micro-tremors between your baseline and each answer. Your score is calibrated to YOU — not a generic population average.

◆ Camera Heart Rate Monitor
Place your fingertip over the rear camera for 15 seconds. Using photoplethysmography (PPG), Auralynx estimates your heart rate and classifies it as Low, Normal, Elevated, or High — with a live PPG waveform displayed in real time.

◆ 45 Built-in Questions Across 5 Categories
Choose from Warm-up, Daily, Work, Relationships, and Fun categories — or type your own custom questions. Hit shuffle for a random pick.

◆ Session History & Trends
Track up to 20 sessions with detailed breakdowns. View your average stress level, confidence percentage, and trend charts right from the home screen.

◆ Signal Mix Breakdown
Go beyond a single number. See a visual breakdown of how much each signal (pitch, energy, tremor) contributed to your overall score, plus a per-question heat strip and bar chart.

◆ Share Your Results
Share your session summary with friends via any app on your phone. Perfect for game nights, team-building, or just a laugh.
