Pick a rhythm
Four breathing rhythms to choose from. Gentle haptics pace each inhale and exhale on your wrist.
A living visualization
Four ambient visuals drift on screen while you breathe — something calm to rest your eyes on, or close them.
One honest score
See how coherent you got with a single number, 0 to 100. No streaks to chase, no noise — just the session.
