Vitalync

Have you ever wondered: is my mental state actually good or bad today?

Not by picking an emoji -- but by using your sleep duration, heart rate variability (HRV), resting heart rate, and step count, calculated by an algorithm, to give you a real answer.

Vitalync is a biometric-based mental state tracking tool. It connects to Apple Health, reads your body data, and through a proprietary Adaptive Integrity Engine algorithm, generates two core metrics every day:

- Mental Clarity -- how sharp your cognitive state is
- Physical Energy -- how well your body has recovered

Not a questionnaire. Not a guess. Data.


-- Core Features --

Adaptive Algorithm Engine
- Four detection modes: Full Spectrum (Sleep+HRV+HR) > Awakening > Drive > Manual
- Interaction effect detection: when sleep deficit + HRV anomaly occur together, the system detects compounded fatigue
- Dynamic baseline: compared against YOUR history, not generic standards
- Fully transparent algorithm: see exactly where every point comes from

3 AI Advisor System
Not one AI, but three with completely different styles:
- Core Analyst -- CBT cognitive behavioral framework, rationally deconstructs your thinking patterns
- Cyber Monk -- mindfulness guidance, helps you find space in the present moment
- Punk Coach -- straight talk, no fluff, action only
Each advisor can see your 30-day data trends (ROOT membership) and give evidence-based suggestions.

State K-Line Chart
Review your mental state trends like a stock K-line chart. 7-day, 30-day, and annual trends at a glance. Each data point can be expanded to view that day's detailed analysis.

Focus Timer and Meditation
7 built-in focus modes (deep work/reading/fitness/meditation...), every minute of timing converts to experience points and currency rewards.
