About This Software

Lung Lab is a calm, beautiful breathing app for your PC. Follow a glowing orb of light as it swells with every breath in and settles with every breath out. Relax after a long day, wind down before sleep, sharpen your focus, or train your breath-hold, all in just a few minutes a day.

Breathe with the light
A living orb guides every breath. Soft tones rise as you inhale, gentle singing-bowl chimes mark each phase, and particles of light flow in and out with your breathing. Watch the orb, or close your eyes and simply follow the sound.

Guided exercises

• Calm Down: longer exhales that help your body settle

• Box Breathing: four equal sides for steady focus

• 4·7·8: a long pause and a slow release, made for bedtime

• Coherence: an even rhythm of about five and a half breaths a minute

• Lung Builder: deep breaths with a hold that grows every round

Choose 2, 5, 10 or 15 minute sessions and pause at any time.

Breath-hold test
A short guided warm-up, then hold as long as feels comfortable. Lung Lab records your personal best and shows how it improves over the weeks.

Six relaxing soundscapes
Rain, Ocean, Wind, Stream, Fireplace and Night: seamless, high-quality ambience you can play under any exercise, with its own volume control.

Build a daily habit

Gentle and safe

Lung Lab is a relaxation and breathing practice tool, not a medical device. It does not diagnose, treat or prevent any condition. If you have a heart or lung condition, are pregnant, or have any health concerns, talk to a doctor before doing breath-hold exercises. Never practise breath-holds in or near water or while driving.
