Discover one of the highest-rated breathing apps designed to help you reduce stress, anxiety, and panic attacks while improving your heart rate variability (HRV) and overall well-being.
Practice guided breathing, train your autonomic nervous system, and experience how a few calm breaths can restore balance, focus, and relaxation.
Breath Ball bridges the gap between breathing apps and HRV apps, combining the best features from both worlds.
Breathwork features you won’t find in most HRV apps:
⭐️
Create your perfect breathing rhythm – The extensive breathing-exercise editor lets you control every inhale, exhale, and pause for truly personalized breathwork or coherent breathing sessions.
⭐️
Relax into sleep – Play calming background sounds that continue after your exercise to help you fall asleep faster and stay relaxed.
⭐️
Practice anywhere – Run breathing exercises or HRV monitoring even with the screen switched off – ideal for meditation or bedtime use.
⭐️
Track your progress & mood – The exercise diary and mood tracker help you see how consistent breathing improves calmness, stress relief, and HRV training results.
⭐️
Exercise with closed eyes – Follow audio guides to stay mindful without looking at the screen.
⭐️
Customize everything – Choose your own colors, brightness, and accessibility settings for visually impaired users.
⭐️
...and much more – explore new ways to build resilience, mindfulness, and relaxation every day.
HRV features you won’t find in other breathing apps:
⭐️
Live biofeedback – Watch your heart rate variability change with every breath. Real-time graphs reveal your cardiac coherence and vagal tone improvements.
⭐️
Detailed time-domain metrics – Track heart rate, RR intervals, RMSSD, SDNN, pNN50, and RSA (acceleration & deceleration) to understand how breathing shapes your body’s rhythm.
⭐️
Frequency-domain insights – View Heart Coherence, VLF, LF, HF, and LF/HF ratios (displayed in percent or ms²) for complete HRV analysis.
⭐️
Interactive Poincaré plot – Visualize your heart rate variability and coherence together for an instant overview of your inner balance.
Included breathing exercises:
⭐️
Deep relaxation through heart coherence – A few minutes of heart-coherent breathing can lead into deep meditative relaxation. Connect a Bluetooth heart rate sensor to view real-time biofeedback while training heart coherence and HRV.
⭐️
478 Breathing for better sleep – Based on Dr. Andrew Weil’s method: inhale 4 s, hold 7 s, exhale 8 s. Combine it with calming background audio to sleep better.
⭐️
Slow-paced breathing for anxiety relief – The go-to technique for panic and anxiety attacks: inhale 4 s, exhale 6 s to restore balance between sympathetic and parasympathetic nervous systems.
⭐️
Box breathing for focus & performance – A technique popularized by US Navy SEALs to build resilience, focus, and stress management: inhale, hold, exhale, hold 4 s each.
⭐️
COPD breathing to catch your breath – Recommended by the COPD Foundation to ease breathlessness. Adjust inhale/exhale timing (2/4 or 3/9 s) with Breath Ball’s intuitive slider for personalized breath training.
Since 2017, Breath Ball has been developed together with its community of therapists and users like you. Your feedback made it the trusted HRV biofeedback and breathwork app it is today.
