PNEO Breathe
Guided breathing for everybody
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Pneo (pronounced "NEE-oh") is a breathwork app built for results. Train your CO2 tolerance, calm your nervous system, and build real breathing fitness with guided techniques and progressive programs.
BREATHE BETTER, PERFORM BETTER
Most people breathe wrong. Shallow, fast, through the mouth. Pneo gives you the tools to fix that with structured breathing techniques and CO2 tolerance training used by athletes, freedivers, and high performers.
