Squair is a mobile application that delivers science-backed breathing protocols directly to users' pockets. The app helps lower heart rate in 90 seconds through controlled breathing techniques that activate the parasympathetic nervous system, providing measurable physiological calm without requiring meditation experience.

The app features Box Breathing for stress management, 4-7-8 breathing for sleep, Kapalabhati for mental clarity, and Power Breathing for energy. It includes a one-tap Zen Button for panic attacks, quick sessions that fit between meetings, and works 100% offline without WiFi. Users can track total sessions, current streaks, and export their data while watching baseline anxiety drop over weeks.

Squair works by leveraging physiological principles where longer exhalations activate the vagus nerve, which directly controls the parasympathetic system. The Box Breathing technique specifically uses a 4-4-4-4 pattern (4 seconds inhale, 4 seconds hold, 4 seconds exhale, 4 seconds hold) that synchronizes the nervous system and drops heart rate 10-15 BPM within 90 seconds.

The benefits include immediate relief from anxiety attacks, stress management between meetings, improved sleep quality, and permanent transformation of baseline stress levels through daily practice. Use cases include managing panic attacks instantly, preparing for presentations, reducing stress during workdays, and improving sleep patterns.

The app targets anxious founders, overwhelmed creators, and anyone who struggles with stress management. It's designed for people who need immediate relief rather than lengthy meditation sessions, with techniques trusted by Navy SEALs, ER physicians, and Olympic athletes.
