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. -- Cyberpunk Identity System -- This is not just a health tool -- it is your cyber alter ego. - Multiple theme skins: from default matrix green to various classic color schemes, each unlocking with your level - Levels and XP: daily logging, focus sessions, and meditation all accumulate XP, continuously unlocking new content - Streak tracking: watching your consecutive days grow is its own positive feedback loop - Compute coins: in-app universal currency for AI conversation credits or character unlocks -- Privacy Commitment -- - All health data is stored only on your device - No tracking, no ads, no data sales - AI analysis sends only anonymized statistical summaries, never raw biometric values - You can delete all your data at any time -- ROOT Membership -- The free version includes complete state tracking, logging, and basic AI analysis. ROOT membership unlocks: - 30-day deep data review + behavioral attribution analysis - Up to 100 AI conversations per day - All 3 AI advisors - Conversation memory (cross-session continuity) - Long-cycle trend charts (30-day/annual) Subscription options: - Monthly: $2.99/month - Annual: $19.99/year (save 44%) - Lifetime: $49.99 one-time purchase Payment will be charged to your Apple ID account.
