About this app

Noxuma Sleep — smart alarm, snore log and simple night tracking. Listens to your night through the phone's microphone, shows you a detailed hypnogram in the morning, and wakes you with a gentle gradual sound. No internet, no account, no data sharing. Free.

WHAT IT DOES
• Sleep monitoring from microphone — movement, breathing patterns, snoring
• Per-minute hypnogram: deep, light, REM, awake
• Stats: sleep efficiency, time to fall asleep, time in each stage
• Smart alarm with smooth 30-second fade-in — no jarring sounds
• 4 built-in alarm sounds
• Optional pairing with SleepPhaser bedside lamp for richer motion data

PRIVACY-FIRST DESIGN
All data stays on your device. The app does not send anything to servers, uses no third-party analytics, requires no account or login. The microphone captures only acoustic features in one-minute windows — no raw audio is ever stored.

WHO IT'S FOR
For anyone who wants to know how they really sleep — without buying hardware, without monthly fees, and without compromising privacy. The app works fully offline and is free.

NOTE
Noxuma Sleep is a wellness app, not a medical device. The data is for personal insight only, not for diagnosis. If you have serious sleep concerns, please consult a doctor.

What’s new

If the system stops tracking overnight, the app now explains it in the morning — and that your alarm was safe.
