Breathwork for iPhone

Breathe with
living light

Kymo is breathwork you want to watch. Every visual moves with your breath, and an optional 60-second fingertip reading shows what each session did.

Your trace

Feel it.
Then see it.

Rest a fingertip over the back camera for 60 seconds before and after a session. Kymo estimates your heart rate and heart-rate variability, so you can see what the session did.

  • Estimates, and labelled that way. Kymo is a wellness app, not a medical device.
  • Processed on your phone. The camera video is never recorded, saved or sent.
  • A morning check-in compares today with your own recent mornings.

25 visuals

Light that moves
with every breath

Each one is drawn live and timed to your breath: it opens as you breathe in, floats while you hold and folds away as you breathe out. Five are free, and all 25 come with Kymo Premium.
