A DIFFERENT KIND OF SLEEP PLATFORM

Your wearable has the data.
Cerene finds the breathing story.

A sleep score tells you how the night went. Cerene places respiratory rate, sleep stages, HRV, recovery, and your own routines on the same timeline—then learns what normal looks like for you.

ONE NIGHT. THREE SYSTEMS.

See the body
as one connected story.

Wearables estimate different signals. Cerene puts them on the same timeline without pretending they are the same measurement.

Breathing rhythm

Respiratory samples reveal your nightly range, stability, and deviation from baseline.

YOUR BREATHING BASELINE

Your normal is more useful
than a generic average.

Cerene learns the range your body returns to, then shows when a night meaningfully moves away from it.

EMERGING PATTERN

Your breathing was most stable on nights with a consistent wind-down.

Eight nights recorded. This is an observation, not a clinical conclusion.

PERSONAL EXPERIMENTS

Change one thing.
Watch the pattern.

Cerene compares groups of nights and tells you when the evidence is early, mixed, or becoming repeatable.

GOOD TO KNOW

Questions, answered clearly.

Cerene does not measure you directly. With your permission, it organizes respiratory, sleep, and recovery estimates from compatible devices and keeps the source visible for every value.

No. Cerene is designed for personal wellness insight and pattern exploration, not diagnosis, screening, or treatment. Persistent or concerning changes should be discussed with a qualified clinician.

The planned Apple connection uses a native iPhone companion to read the HealthKit categories you explicitly authorize, such as sleep stages and sleeping respiratory rate.

With OAuth permission, WHOOP can provide sleep performance, efficiency, respiratory rate, recovery, HRV, resting heart rate, and other supported measurements.

No. Cerene describes associations in your recorded nights. It labels early and limited patterns clearly and does not claim that a routine caused an outcome.

Only to provide the Cerene experience you request. Health information is not sold, used for advertising, or hidden behind opaque source labels.
