Science-Based Breathing
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
25,000 breaths a day. Most of them wrong. Guided patterns,
BOLT Score tracking & Nestor's science in your pocket.
Most people breathe 25,000 times a day.
Almost all of them wrong.
Rumi Breathing is a science-based practice companion built
on James Nestor's landmark research into nasal breathing,
CO₂ tolerance, and the lost art of breathing well.
BREATHE
Guided patterns — Resonance, Coherent, Box, 4-7-8, and more.
Breathing at 5.5 breaths per minute synchronises your heart
rate variability to its resonance frequency. The effect on
HRV, blood pressure, and anxiety is measurable within
a single session.
LEARN
A science library built from Nestor's research: nitric oxide,
the Bohr Effect, the Stanford experiment, and the
mouth-breathing epidemic reshaping modern skulls.
TRAIN
Daily exercises and multi-day programs: Nose Unblocking,
CO₂ Tolerance, Mouth Tape, and Breath Awareness.
MEASURE
The BOLT Score reveals your CO₂ tolerance — the single most
predictive measure of breathing efficiency. Track it over time.
Your nose is a pharmacy. Start using it.
