## What is 37 Breaths?

A simple, focused breathing pacer. Pick a pattern — Box (4-4-4-4) for steadying focus, 4-7-8 for winding down, or Coherent (5-5) for slow, even breathing — choose a duration, and follow the circle. Gentle haptics mark each phase so you can practice with your eyes closed. Sessions always end on a completed breath. No account, no ads, no tracking: your session stats stay on your phone.
