Panic SOS is here: instant relief for anxious moments. Three emergency breathing tools, always unlimited, always with you.
CALM YOUR NERVOUS SYSTEM IN MINUTES
Based on 500+ peer-reviewed studies on heart coherence. No hardware required - just your breath.
THE SCIENCE
When you breathe at exactly 6 breaths per minute, something measurable happens: your heart rhythm, blood pressure waves, and nervous system synchronize. Scientists call this "heart coherence" - a state documented in hundreds of peer-reviewed studies for 30 years.
Add a genuine positive emotion - real gratitude or appreciation - and the effect deepens. Cortisol drops. HRV rises. Your nervous system shifts from fight-or-flight to rest-and-repair.
TWO DAILY PROTOCOLS
MORNING ACTIVATION (5 MIN)
Tone your vagus nerve and prime your nervous system for the day.
- Guided humming - activates the vagus nerve through vibration
- Extended exhale breathing - 4 in, 8 out, 5 cycles
- Cold water reset - 30-second guided face immersion
EVENING COHERENCE (7 MIN)
Enter heart coherence in the optimal pre-sleep window.
- Resonant breathing at 6 breaths per minute
- Heart focus visualization
- Positive emotion anchoring - deepens and sustains the coherence state
QUICK RESET (3 MIN)
For stressful moments. Anywhere, anytime. No setup required.
11 BREATHING PROTOCOLS
Box Breathing, Physiological Sigh, 4-7-8 Breathing, Alternate Nostril, Energizing Breath, Deep Coherence - each with the science behind why it works, accessible in one tap.
TRACK YOUR PRACTICE
- Coherence score after every session
- Daily practice calendar with streak tracking
- Session history and total practice minutes
- Weekly coherence trend
WHY THIS IS DIFFERENT
Most breathing apps are timers - a circle that grows and shrinks, nothing more. Heart Coherence:
- Combines vagus nerve activation WITH heart coherence breathing - no other app does both
- Includes positive emotion anchoring, the step that deepens and sustains the state
- Explains the science behind every protocol in plain language
- Works without hardware - and shows real heart rate proof automatically if you wear an Apple Watch
- Builds a measurable daily practice you can see growing
No device required. No subscription to a seminar. Just 8 minutes - and the nerve that connects your brain to your heart. (Apple Watch owners get free post-session heart rate insights, automatically.)
