Nefesly / Breathing
Breathe with Pofi
Breathe in as Pofi puffs up, breathe out as it settles. There are three paces; pick the one that feels comfortable. This page only keeps the pace.
If you feel dizzy or short of breath, stop and breathe normally. This is an exercise pace, not medical advice.
This page stores nothing; everything happens in your browser.
The same paces are on the breathing screen of the Nefesly app. Support
