Coherent Breathing 5-5 Timer
Coherent breathing — also called resonance breathing — uses a steady 5-second inhale and 5-second exhale, giving 6 breaths per minute. Research links this rate to maximum heart-rate variability (HRV), reduced blood pressure, and improved parasympathetic (rest-and-digest) tone. It's the rate Apple Watch uses in its built-in Breathe app.
How the visualization works
The circular frame represents continuous, endless flow — no edges, no holds. The amber dot makes one full revolution around the circle every 10 seconds. During inhale, two subtle streams flow UP into the nostrils. During exhale, the mouth opens and a stream flows DOWN past the chin. Match your breath to the dot's smooth motion.
