Snozzt

Snore detection, coughing and sleep-talk clips, full Apple Health sync, and now sleep stages from your Apple Watch — all analyzed on your device.

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.
