serein

one breath,
made visible

breathe once. your pace and steadiness become a living glass orb — a five-second check-in that settles into a quiet diary.

Serein diary of living moments — a collection of breath orbs

five seconds

one breath a day is enough. a gentle reminder keeps the ritual alive without asking for more.

private by design

the microphone listens only while you breathe. everything is analyzed on your iphone — no audio is ever recorded or stored.

a living diary

each breath settles into your diary as a small weather system you can return to, day after day.
