Box Breathing Timer
Built to help visualize the box breathing technique.
This tool provides a simple visual guide for the box breathing technique, moving in a square pattern to help pace your breathing: inhale for 4 seconds, hold for 4 seconds, exhale for 4 seconds, hold again for 4 seconds, then repeat.
Intervals are optionally accompanied by audio to help focus without looking at the screen and can be shortened if 4 seconds is too long to start.
