## What is HRV Flow?

Your morning recovery score from 7 Apple Watch signals. Completely free.

■ Daily Recovery Score (0-100)
A single morning score calculated from 7 signals your Apple Watch already records:
・Wake-up HRV
・Resting heart rate
・Respiratory rate (sleep average)
・Sleep duration
・Sleep stages (Deep + REM quality)
・Sleep heart rate
・Bedtime consistency

No extra wearables, no subscriptions — same input coverage as Whoop / Oura, just from your Apple Watch. Tap "Why this score?" to see each signal's contribution.

■ 11 Breathing Patterns
Five categories of breathing techniques for every moment: relaxation, focus, emergency stress relief, and sleep.

・4-7-8 Breathing (Relaxation)
・Box Breathing (Focus)
・Coherent Breathing (HRV Optimization)
・Physiological Sigh (Instant Calm)
・SOS Breathing, Quick Breathing, Night Breathing, and more

■ Post-Session Heart Rate Feedback
See how your heart rate changed before and after each session. Understanding your body's response keeps you motivated.

■ HRV Monitoring
Automatically captures and visualizes HRV (Heart Rate Variability) from Apple Watch. Track your daily condition through HRV trends.

■ Morning Condition History
View 7-day trends of wake-up HRV, resting heart rate, and sleep duration in charts. Small daily changes reveal your body's rhythm.

■ Habit Tracking
Record every breathing session. Streaks and weekly charts help you build a lasting habit, at your own pace.

■ Smart Notifications
Gentle reminders when stress is elevated or at your scheduled times. Notifications are automatically suppressed during sleep. Morning condition alerts help you start each day with awareness.
