Calm — Breathing Pacer

Calm is a free breathing pacer that guides you through evidence-based breathing exercises, right in your browser. No app to download, no sign-up required—just open it and start with your preferred breathing technique. Whether you need a moment of calm during a busy workday or a wind-down ritual before sleep, this breathing exercise tool lets you practice at your own pace.

The tool includes multiple breathing patterns, including the popular 4-7-8 technique and box breathing, each designed to activate your body's relaxation response. The 4-7-8 method guides you to inhale for 4 counts, hold for 7, and exhale for 8. Box breathing uses equal counts of 4-4-4-4, creating a balanced rhythm that many find deeply centering. Your breathing pacer keeps you on track with gentle visual and audio cues.

Every session is private—your data never leaves your device. The warm, intuitive interface makes these breathing exercises accessible whether you're a beginner or returning to a regular calm practice. Just click start, follow the guide, and let your body naturally respond to the rhythm of your breathing pacer. It's the simplest, most private way to add a meaningful breathing exercise to your daily routine.
