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. 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.

What’s new

New: Trends. The chart icon in History opens your last 7, 30 or 90 nights side by side — how long you slept, what each night was made of, and how the averages moved against the period before.

Nights the system cut short are still drawn, but never counted into the averages, so a phone that killed the app cannot make your sleep look worse than it was.
