Planck Breathe

Planck Breathe is a guided breathwork app for people who want a calm timer, not a
wellness platform.

Pick a pattern. Watch the circle grow on the inhale, hold, shrink on the exhale, and
rest. Stop when you are done. The session goes into your history.

PATTERNS
Calm. Equal 5-5 rhythm. A good starting point.
Box. 4-4-4-4 square breathing for focus and calm.
4-7-8. Deep relaxation. Excellent before sleep.
Energize. 2:1 exhale ratio. Boosts alertness.
Ujjayi. Ocean breath with soft throat restriction.
Sama Vritti. Equal breath that balances the nervous system.
Nadi Shodhana. Alternate nostril cadence. Clears the mind.
Bhramari. Humming bee breath. Hum softly on the exhale.

NOT MEDICAL ADVICE
Planck Breathe is a practice tool, not a medical device. If you have a respiratory
condition, cardiovascular condition, are pregnant, or have a history of panic attacks,
talk to a qualified clinician before starting any structured breathwork practice.
Stop and rest if you feel lightheaded.

THE PLANCK SERIES
Planck Breathe is part of a small family of focused single purpose apps. Same dark
aesthetic, same hbar mark, same idea: do one thing, do it well, then get out of the
way.
