Inside the sound

Two tones. One beat you feel.

In headphones each ear gets its own tone. Your brain hears the 10 Hz gap between them as a slow pulse. On a speaker, CoFlow plays the pulse directly, so it works without headphones too.

Haptics guide your breath — eyes closed is fine

Breathe in
It listens back

Your heart sets the pace.

With AirPods Pro or Apple Watch, CoFlow reads your heart rate as you go and adapts the session to match. Every session saves to Apple Health as Mindful Minutes.

Find your tone

Hum once. Aris builds on it.

Hum any comfortable note for a few seconds. CoFlow finds its pitch and keeps just the number — never your voice. Aris uses it as the base of your sessions when it fits.

The Living Lotus

Every session leaves a petal.

Your lotus grows with the time you give it: forty-one petals in four rings, opened one session at a time.
