Box Breathing & 4 vs Falcon Interval Timer

The app provides a simple timer to guide your box breathing practice or 4-7-8s exercise. Box breathing is a technique used to calm yourself down using a simple four-second cycle for each step: inhale, hold, exhale, hold – and repeat. Also known as Navy SEAL breathing or tactical breathing.
