BreathBox — Breathing Break

A quiet breathing break in your side panel. Box, 4-7-8 and coherent breathing, gentle sounds and optional reminders. Offline.

Take a quiet breathing break without leaving your browser. BreathBox lives in Chrome’s side panel: choose a rhythm and duration, then follow the gently moving orb. • Box breathing 4-4-4-4, the 4-7-8 rhythm, and coherent breathing 5-5. • Sessions of 2, 5 or 10 minutes. • Smooth animation and soft chimes you can turn off. • Click the orb to start, pause or resume. • Light and dark themes follow your system. • Optional reminders every 30, 60 or 90 minutes, off by default. • No ads, account or subscription. Works offline. Closing the panel pauses your practice. Open it again and resume when you are ready. Panels in different Chrome windows share one practice. Your preferences and practice history stay in your browser profile. BreathBox does not read web pages, track browsing or send data to a server. Breathe gently. Stop if you feel dizzy or uncomfortable. BreathBox is a relaxation tool, not a medical device.
