Snozzt is a sleep tracker that respects your privacy

Every sound captured during the night is analyzed on your device — no uploads, no cloud accounts required,

no audio leaves your phone.

Place your phone on the nightstand, plug it in, lock the screen, and go to sleep

In the morning, open Snozzt to see what happened during the night: when you

snored, when you coughed, when you talked in your sleep, and how the sound level changed across the hours.

Detection runs entirely on-device using Apple's built-in sound classifier

Nothing is sent to a server, ever.

OPTIONAL AUDIO CLIPS

Turn on "Record snore, cough & sleep talk audio" in Settings to keep short clips of detected events

Tap any event in History to play it back

Clips are stored

only on your phone and are deleted automatically when you delete the session.

APPLE HEALTH INTEGRATION

Snozzt writes each finished sleep session to Apple Health, so it shows up alongside data from any other sleep app or wearable in your Health timeline

Audio is

never written to Health.

EXTRAS

Daily bedtime reminder at the time you choose

Wake-up alarm

Sign in with Apple (optional — recording works without an account)

Multilingual: English, 日本語, 한국어, 简体中文, 繁體中文

PRIVACY, IN PLAIN ENGLISH

We don't have a backend

We can't see your data

We don't run analytics

There are no third-party SDKs

The microphone is used only when you start a session, and

the audio is processed in real time and discarded — except for the short event clips you explicitly opt in to record, which stay on your phone.
