Introducing "Target Mode": Set a starting pace and a target pace so you can slow your breathing over time, as you relax.
BREATHWORK GUIDED BY MUSIC
Allos combines engaging music with a simple, science-based breathing practice that helps you quickly reduce stress, improve focus, and build resilience.
THE POWER OF RESONANCE FREQUENCY BREATHING
The practice of gentle, slow breathing at your resonant frequency is a unique form of breathwork that syncs your breath to the natural rhythm of your heart and nervous system.
MUSIC TO MATCH YOUR MOOD
We’ve created a library of customizable music by award-winning composers and producers in multiple genres to guide your breathing practice:
- Lofi/Chill
- Upbeat/Electronic
- Acoustic/World
- Classical/Orchestral
- Ambient/Downtempo
- Atmospheric/Soundscapes
- Nature/Environmental
Browse through the library to find the track that feels right for you in the moment or matches the goal of what you want to feel instead.
CUSTOMIZED TO YOUR IDEAL BREATHING RATE
Explore different breathing rates to discover your unique resonance frequency. Adjust the inhale/exhale ratio for activation or down regulation. The music and visuals automatically adapt to beat at that precise breathing rate and ratio.
SET YOUR TARGET PACE
Use Target Mode to set a starting pace and a target pace so you can slowly reach your ideal breathing rate over time as you relax.
SCIENCE-BASED PROTOCOL
Allos is inspired by the science of HRV biofeedback and resonance frequency breathing. We designed the app to support these practices and to work alongside most HRV biofeedback apps. The breath pacing offered in the app is informed by research showing that slow-paced breathing exercises at your personal resonance frequency may help:
- Reduce stress
- Support emotional balance and self-regulation
- Promote mental clarity and focus
- Prepare for restful sleep
- Encourage post-exercise recovery
- Build resilience to stress
Note: This app is intended for general wellness and does not diagnose, treat, or prevent any medical condition.
