Noxuma Sleep

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. Noxuma works fully for free with your phone. Optionally connect Sleep Phaser lamps to explore sleep for more people in your household. The app also includes a growing library of practical, visual Sleep Tips. No account, no ads, works offline. 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
• 12 built-in alarm sounds, or your own audio file
• Sleep guide: visual cards with practical, source-backed tips

PRIVACY-FIRST DESIGN
Your nights stay on your phone. Sleep data and hypnograms are never uploaded, and there is no account or login. The microphone is analysed on the device in one-minute windows; raw audio is never recorded or sent. Short snore clips are saved only if you turn them on, and they stay on the phone too.
To keep the app reliable, it sends anonymous technical diagnostics: crash and error reports, and a small launch ping with a random installation ID, the app version and the number of nights started. They never contain audio, sleep data or anything you typed. Anything else leaves your phone only when you choose to share it.

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.

Recent changes:
New: “Get ready for sleep” — one tap plays Breathing or Soft noise for 5–15 minutes, the sound fades out and the app moves into measuring the night by itself.

New: “Suggest a feature” under Settings → Help — leave an e-mail and we will tell you what happens to your idea.

The Sleep guide now lives in Settings only.

Fixed: the back gesture during a night no longer ends it.

When the microphone delivers only silence, the app says what to check (Android: “Microphone access” toggle).
