Description

Most breathing apps just play a timer. Respirix connects to your heart rate strap (optional) and shows whether your breathing is actually working in real time. Live HRV coherence feedback, a guided resonance frequency finder, and research-backed protocols. No subscription. No account. Just results. Works without a heart rate strap.

GUIDED BREATHING MADE SIMPLE

Choose from four research-backed breathing protocols or create your own custom pattern. Set your duration, hit start, and let the voice cues and visual pacer guide each breath. Put your phone down, close your eyes, and relax.

BREATHING PROTOCOLS

Resonance (4.5s in, 5.5s out) - Maximize HRV amplitude at ~6 breaths per minute

Extended Exhale (4s in, 6s out) - Activate relaxation through prolonged exhalation

Slow Diaphragmatic (4s in, 2s hold, 5s out, 2s hold) - Stabilize your autonomic nervous system

HRV Biofeedback (4s in, 2s hold, 6s out, 2s hold) - Long-term autonomic retraining with live feedback

Custom - Configure your own protocols with inhale, hold, and exhale durations

FIND YOUR RATE

Everyone has a breathing speed where their body relaxes most deeply. A guided assessment tests six different speeds, measures your heart rhythm at each one, and identifies your personal resonance frequency. Your optimal rate is then used automatically in future sessions.

Real-time HRV coherence score with visual gauge

Adaptive breathing rate that adjusts to your coherence in real time

RMSSD tracking (heart rate variability metric)
