Connect to Natural Rhythms & Improve Resilience in Your Bodymind
The only HRV app that trains adaptive resilience through fractal variability—not fixed breathing patterns. Perfect for managing stress, improving recovery, and optimizing performance.
Track Your Body's Adaptability
Unlike basic HRV (measured in milliseconds), DFA alpha reveals your nervous system's adaptability—how well you balance calm focus with quick responsiveness. Alpha values near 1.0 indicate optimal adaptivity, while higher values signal tension and lower values indicate recovery mode.
What Your DFA Alpha Score Means
Unlike basic HRV (measured in milliseconds), DFA alpha reveals your nervous system's ADAPTABILITY—how well you balance calm focus with quick responsiveness.
Your nervous system is in overdrive. Time for recovery-focused sessions.
Perfect balance. You're ready for challenges and can return to calm quickly.
Your body is consolidating gains. Light activity or rest recommended.
💡 Key Insight: Unlike basic HRV (measured in milliseconds), DFA alpha reveals your nervous system's ADAPTABILITY—how well you balance calm focus with quick responsiveness.
How SomaSync Helps You
Research shows that fractal variability training can have profound effects on anxiety, sleep, recovery, and long-term nervous system resilience.

How SomaSync Works: Science Meets Practice
The 4-step adaptive training process that builds lasting nervous system resilience through naturally variable rhythms.
Choose Your Training Protocol
Select from research-backed presets: Deep Breathing (stress relief), Performance Prep, Recovery Mode, or Sleep Preparation. Each uses fractal algorithms generating naturally variable rhythms.
Experience Multi-Modal Guidance
Feel, see, and hear your training in real-time with haptic feedback, visual cues, and audio signals. Your body learns through multiple sensory channels.
Follow the Variable Rhythm
Unlike fixed patterns, SomaSync varies each breath: 6 seconds, then 3 seconds, then 7 seconds. Your nervous system learns to handle CHANGE—the fundamental skill for resilience.
Track Your Adaptive Progress
Monitor daily DFA alpha trends, session insights, weekly resilience scores, and get personalized AI-guided recommendations. Real data. Real progress.
Natural Rhythm Connection
Reconnect with Life's Inherent Patterns
Fractal rhythms mirror the variability found throughout nature. Your body evolved for variability—modern life demands rigid schedules and constant alertness. Fractal training helps you return to your natural adaptive state, the state where humans thrive.
Healthy Heartbeats
Variable intervals that respond to breath, thoughts, and movement
Water Patterns
Ocean waves and rivers follow natural fractal patterns
Plant Growth Patterns
Fractal variability creating strength through adaptation
Weather Patterns
Cyclical yet unique—adaptable systems thriving in change
Your Body Evolved for Variability
Modern life demands rigid schedules, constant alertness, and suppressed rhythms. Your nervous system wasn't designed for this. Fractal training helps you return to your natural adaptive state—the state where humans thrive.
Perfect Apple Watch Integration

What Is Fractal Variability?
Real-time variability patterns inspired by healthy heart patterns entraining your body's rhythms
Sample Fractal Time Series
Fractal variability pattern emulating the heartbeat. When it beats slowly, it also has fast moments. When it beats fast, it also has slow moments. It is affected by both parasympathetic and sympathetic nervous system and it listens to both. It can react to the smallest impulse but also to a big impact.

What Users Are Saying: Real Results
Join thousands of users who have discovered that true resilience isn't about staying calm—it's about learning to adapt.
"SomaSync helps me focus on adaptivity, resilience, and recovery in my practice. Its built-in breathing exercises help bring the body to the optimal state"
"Most of HRV metrics focus on the value rather than on variability. SomaSync provides unique insights about the fractal nature of HRV, which goes beyond the mere HR zone training"
"The science behind fractal variability is fascinating, and SomaSync makes it accessible. My students report deeper states of relaxation and better stress management."

Frequently Asked Questions
How is SomaSync different from other breathing apps?
Most breathing apps use fixed patterns (inhale 4, hold 7, exhale 8). These create temporary relaxation. SomaSync uses variable fractal rhythms that train your nervous system to be BOTH calm AND responsive—building permanent adaptability, not just temporary calm.
What is DFA alpha and why does it matter?
DFA alpha measures the fractal patterns in your heart rate variability. A value around 1.0 indicates optimal adaptability—your nervous system can activate for challenges and return to calm efficiently. Higher values indicate tension, lower values indicate deep recovery. It's the best metric for true nervous system resilience.
Do I need the Polar H10 chest strap?
No, SomaSync works with Apple Watch alone for general tracking. However, for clinical-grade accuracy and precise DFA alpha measurement, we strongly recommend the Polar H10. Athletes and serious practitioners should use Polar H10 for optimal results.
How accurate is Apple Watch for HRV?
Apple Watch is excellent for tracking HRV trends over time—seeing if your resilience is improving week-to-week. For absolute accuracy and precise DFA alpha values, the Polar H10 chest strap provides research-grade data (99.6% accurate vs clinical EKG).
Can this help with anxiety and stress?
Yes. Fractal breathing trains your vagus nerve, which activates your parasympathetic (rest-and-digest) nervous system. Unlike fixed breathing that only creates temporary calm, variable training teaches your nervous system to self-regulate—reducing anxiety attacks, racing thoughts, and chronic stress over time.
How quickly will I see results?
Many users report feeling calmer after their first 5-minute session. For measurable changes in DFA alpha and HRV trends, most people see improvement within 2-3 weeks of daily practice. Long-term resilience builds over 8-12 weeks of consistent training.
How long should I train each day?
Start with 5 minutes daily. As you build capacity, you can do multiple sessions: Morning (5-10 min for performance readiness), Midday (3-5 min for stress reset), Evening (10-15 min for sleep preparation). Quality matters more than quantity.
What research supports fractal variability training?
DFA alpha analysis is well-established in cardiology and sports science. Research shows that fractal HRV patterns predict cardiovascular health, athletic performance, and stress resilience. Key studies include work on heart rate complexity (Peng et al., Goldberger et al.) and vagus nerve training (Porges' Polyvagal Theory).
