VagalFlow

In a world full of noise, find stillness with your body. Red light, breathing resonance, and pulse awareness — a quiet practice for your nervous system.

VagalFlow is a personal wellness app for nervous system regulation, guiding you through five stages of quiet practice. Five stages. One complete session:

Calibration Using your last 7 days of HRV data, VagalFlow calculates your personal breathing resonance frequency — the pace that works best for your body right now.

Prime Red screen light guides your body into a relaxed state before breathwork begins. Close your eyes or keep them half-open; the light works through your eyelids.

Sync Follow a circular breathing guide at your personalized pace for 5 minutes. Your Apple Watch streams live heart rate data so you can watch your body respond.

Interoception Press two fingers gently on your pulse and count heartbeats for 60 seconds, then compare with your Apple Watch reading. A practice in sensing your body's internal signals.

Record Save your session as Mindfulness time in Apple Health. Track patterns over time and notice how your body changes with regular practice.

【Who This Is For】 Anyone feeling chronically tense who wants to reconnect with their body · Those curious about autonomic nervous system regulation and vagal training · People who prefer quiet, non-verbal self-care practices · Apple Watch users who want meaningful health tracking
