NIGHTSONG

Any phone becomes
the sensor.

Nightsong turns how you breathe at night into the Somnus Index, the wellness side of the Somnus platform. It listens and it scores; it does not diagnose.

How it works

Nightsong listens to how you actually breathe at night, using BSA, the on-device acoustic breathing and snoring engine. No wearable, no hardware, nothing to buy.

You sleep. Your phone listens. The platform begins to understand your nights.

The Somnus Index

The Somnus Index is one plain-language wellness number that moves with you, night over night. Think of it as a credit score for your breathing.

The Somnus Index is a wellness metric under the FDA General Wellness policy. Not a medical device.

Deterministic edge compute

Every night is scored on your device, in real time. The same inputs always produce the same number. Nothing estimated, nothing simulated, no cloud round trip.

Your data is your data

The analysis happens on the phone in your hand. Your recordings stay on your device. You decide if anything is ever shared.

Where Nightsong sits in the loop

Nightsong is the Sense node of the Somnus platform, the zero-cost top of the funnel. See how sensing connects to scoring, routing, therapy, and outcomes on the platform page.
