Breathwork Tools is a free AI-powered breathwork app that runs in your browser. No app store, no download, no subscription. It's a Progressive Web App (PWA) that installs to your home screen and works offline — with an AI coaching layer that personalizes every session.
Most breathwork apps are content libraries: a list of pre-recorded sessions you scroll through. This is fundamentally backward. You don't need 500 sessions to choose from — you need one perfect session for right now. The AI builds that session on the fly based on your current state and goals.
The app includes 9 core breathing patterns (box, coherence, 4-7-8, physiological sigh, extended exhale, resonance, triangle, power breathing, and energizing 4-2-8), customizable durations from 1 to 30 minutes, visual pacing, audio cues, and session tracking. The AI layer adds intelligent pattern selection, adaptive pacing, and personalized progression.
It works on every device: iPhone, Android, iPad, Mac, Windows, ChromeOS. Install it to your home screen for instant access, or just visit the URL. Your sessions sync across devices when you sign in.
