Finally See How Foods Affect YOUR Body

Food Sensitivity Detection

Traditional food tracking apps ask you to log calories. VitalWhy does something different: it watches how your body actually responds to what you eat — through your heart rate, HRV, sleep quality, energy, and more.

  • Extended watch windows: Gluten reactions can take up to 72 hours. Dairy up to 24 hours. VitalWhy tracks across the full reaction timeline, not just the hour after you eat.
  • Multi-window analysis: Checks your acute response, next-morning impact, and extended effects separately
  • Cumulative exposure tracking: Monitors your 7-day, 14-day, and 30-day exposure levels — sometimes it's not one meal, it's the buildup over days
  • Symptom tracking: Log bloating, brain fog, fatigue, skin reactions, headaches, and more alongside biometric data
  • Food family grouping: Discovers patterns across related foods (all nightshades, all dairy, all gluten grains)
  • Guided elimination experiments: Structured frameworks with daily check-ins for removing and reintroducing suspected trigger foods

If you've spent years wondering why you feel terrible and doctors can't find anything wrong — your data might have the answer.

See the Measured Impact. No Lectures.

Substance Impact & Recovery

Whether you're cutting back, quitting, or just curious about what alcohol, caffeine, cannabis, or other substances actually do to your body — VitalWhy shows you the measured truth from your own biometrics.

  • Dose-response tracking: See how 1 drink vs. 3 drinks affects your sleep, HRV, and next-day energy differently
  • Sobriety streaks & milestones: Track your progress with compassionate milestone celebrations — and no shame if you reset
  • Trigger awareness: Identify what situations (stress, social pressure, boredom, time of day) precede substance use
  • Recovery pattern detection: See how your biometrics improve over days and weeks of reduced use
  • Flexible goals: Quit, reduce frequency, set a weekly budget, or just build awareness — your pace, your choice

VitalWhy never tells you what to do. It shows you what your body already knows.

Your Mental Health, Made Visible

Mental Health & Mood Tracking

VitalWhy doesn't just track physical biometrics — it helps you understand the connection between your mental state and your body. Track your mood, log therapy sessions, and discover patterns you never noticed.

  • Mood journaling: Log your mood on a 1-10 scale, select emotions (anxious, hopeful, calm, overwhelmed), and identify triggers
  • Therapy session logging: Track pre/post session mood, homework assignments, key insights, and progress over time
  • Mood-biometric correlations: See how your HRV, sleep, and activity affect your mental state — and vice versa
  • Pattern detection: Weekly insights like "Your mood tends to dip on Mondays" or "Exercise correlates with +2.3 mood points"
  • Crisis awareness: When patterns suggest you might be struggling, VitalWhy gently offers support resources — never alarming, always caring
  • Personal wins: Surfaces your positive patterns — "The last 5 times you meditated, your HRV improved 18%"

When things are going well, VitalWhy celebrates with you. When things get hard, it gently shows evidence from your own history — not advice, not judgment, just your patterns made visible.

We Ask. You Answer. Patterns Emerge.

Smart Prompts

Instead of asking you to constantly log everything, VitalWhy only reaches out when something meaningful happens in your body.

  • Context-aware prompts based on detected changes in your biometrics
  • Shows you what shifted in simple, human language
  • Quick-tap responses for common events — no typing required
  • Learns from your history to suggest the most likely causes first

This gentle approach captures the important data without creating tracking fatigue or making health feel like homework.

Having a Craving? We've Got You.

Craving Intervention & Healthy Redirects

When a craving hits, VitalWhy doesn't judge — it helps. Log what you're craving, get a healthy alternative, and later see the biometric proof that the redirect actually worked.

  • "I wanted X but did Y": Log the craving and what you did instead — a walk, calling a friend, a healthy snack, breathing exercises
  • Healthy redirect suggestions: Walk outside, call a loved one, 4-7-8 breathing, cold water, stretching, journaling, and more
  • Biometric proof: After the redirect, VitalWhy shows you how your body responded — "Your HRV improved 12% after that walk"
  • Proactive risk detection: Recognizes stress patterns and time-of-day triggers to offer support before cravings hit
  • Pattern reports: Monthly summaries showing which redirects work best for you and when cravings are strongest

Over time, you build a personal toolkit of what actually works for your body — backed by data, not willpower alone.

Your Personal Pattern Finder

Correlation Engine

This is where VitalWhy connects the dots. Over weeks of data, it finds the patterns that explain your unique responses — things you might never have noticed on your own.

  • Compares how you feel on days with certain events vs. days without
  • Requires 3+ occurrences before surfacing a pattern — no false alarms
  • Tracks impact across sleep, clarity, stress, energy, mood, and all your biometrics
  • Watches biometric changes from 1 hour before to 2 hours after events
  • Works in both directions: how events affect you AND what your body state predicts about your choices

The answers are in your data. VitalWhy just makes them visible.

Works With Your Devices

Health Connect — 30+ Data Types

VitalWhy connects to Android's Health Connect platform, pulling data from whatever devices you already own. No special hardware required.

  • We recommend Garmin watches for continuous HRV data; other devices share nightly HRV only
  • Reads heart rate, HRV, blood pressure, SpO2, sleep, weight, body composition, exercise, and more
  • Automatic background sync every 15 minutes
  • Secure, permission-based data access — you control what VitalWhy can see

We Notice When Something Changes

Biometric Awareness

VitalWhy quietly compares your recent readings against your personal 7-day baseline. When something meaningful changes, it lets you know — gently.

  • HRV: Notices changes of ±20% from your baseline
  • Heart Rate: Catches shifts of ±10 bpm
  • Temperature: Detects changes of ±0.4°F
  • SpO2: Watches for ±2% oxygen variation

VitalWhy never says "warning" — it says "something shifted" and asks what happened. Your body is always communicating. VitalWhy helps you listen.

Daily Insights

Blood Pressure Analysis

VitalWhy goes beyond recording readings. It builds daily summaries that reveal how your lifestyle affects your numbers.

  • Daily aggregation: average, max, min, morning vs. evening readings
  • Mean Arterial Pressure (MAP) and pulse pressure calculations
  • Medication pattern correlation — compare readings with vs. without medication events
  • Personal baseline comparison — always YOUR pattern, never clinical thresholds

See how sodium, exercise, stress, alcohol, and sleep affect your blood pressure across weeks and months.

Personalized Targets

Hydration Tracking

Water intake affects every biometric VitalWhy measures. Unlike generic "8 glasses a day" targets, VitalWhy calculates YOUR personalized target.

  • Personalized daily target based on weight, age, sex, and activity level
  • Dynamic adjustments for exercise, caffeine, alcohol, and heat exposure
  • 2-tap quick-log on the Home screen (8 oz, 16 oz, 24 oz, or custom)
  • Bidirectional correlations: how hydration affects your biometrics AND how events affect your hydration
  • Streak tracking, progress ring, and smart reminders when you fall behind

Overnight Insights

SpO2 & Sleep Breathing Analysis

VitalWhy builds nightly SpO2 summaries that surface patterns in your overnight oxygen levels that simple charts miss.

  • Nightly average, minimum, and variability tracking
  • Desaturation event counting — how many times SpO2 dropped significantly
  • Oxygen Desaturation Index (ODI) per hour of sleep
  • Time spent below 90% and 95% thresholds
  • Correlates alcohol, sleeping position, altitude, and congestion with overnight SpO2 patterns

Environmental Intelligence

Weather & Air Quality Correlation

Your body doesn't exist in a vacuum. Temperature, humidity, barometric pressure, air quality, and pollen levels all affect how you feel. VitalWhy tracks these automatically.

  • Automatic weather snapshots: temperature, humidity, pressure, UV index, wind
  • Air quality monitoring: PM2.5, PM10, ozone, NO2, SO2, CO, EPA AQI
  • Pollen indices: tree, grass, and weed pollen levels
  • Correlates environmental conditions with your HR, HRV, sleep, and mood
  • Discover if barometric pressure drops affect your migraines, or if high PM2.5 days correlate with lower HRV
