Cortisol Meter - Stress & HRV Indicator

Is that unread email spiking your cortisol? Turn the meme into reality with Cortisol Meter! Whether you are genuinely trying to optimize your physiological recovery, or just want to confirm that a minor daily inconvenience has thrown you into a state of high alarm, this standalone Connect IQ app is here to help. Cortisol Meter visualizes your Garmin Stress Index—derived from heart rate variability (HRV) markers—as a clean, relative indicator of cortisol activity. Rather than just reading a raw number, the app translates your autonomic nervous system responses into six intuitive zones ranging from resting recovery ("low cortisol" vibe check) to full fight-or-flight states. Designed specifically for round AMOLED screens, Cortisol Meter delivers a premium dashboard look on your wrist, providing instant feedback on your current recovery, strain, and mental load. KEY FEATURES: • Viral Audio Playback (New!): Press the START button or tap the screen to play (or stop) the iconic "Low Cortisol Song" ("Ai Đưa Em Về" - TIA ft. Lê Thiện Hiếu) directly from your watch's buzzer! • Real-time HRV Integration: Uses the device's native ActivityMonitor and Sensor History APIs to gather your actual stress score immediately on launch. • 6-Zone Colored Dial: Clean visual representation of cortisol levels (Low, Optimal, Normal, Elevated, High, Extreme). • Dual Themes: Easily swap between AMOLED Dark Mode (pure black) and high-contrast Light Mode (white). • Touch & Button Controls: Toggle screen themes using the physical UP/DOWN buttons or a simple vertical swipe on the touchscreen. • Premium Fluid Needle: Tapered analog needle that changes color dynamically based on your theme. HOW TO USE: 1. Launch the app from your activities/apps menu. 2. The dial shows your current cortisol/stress score. 3. Tap the screen or press the START button to toggle the "Low Cortisol Song" melody. 4. Swipe UP/DOWN on the screen or press the physical UP/DOWN bezel buttons to switch between Dark and Light mode themes. DISCLAIMER: This application is for informational and educational purposes only.
