What it does
Your night at a glance
Per-minute hypnogram
In the morning you see when you fell asleep, when sleep was light, deep or REM, and when you were awake. Plus sleep efficiency and time to fall asleep.
Smart alarm
Set a window and the app wakes you in lighter sleep. Or pick an exact time. The sound fades in over 30 seconds, with 12 sounds to choose from or your own.
Sounds of the night
The app notes possible snoring and other sounds. You can optionally keep short clips and listen to them.
Sleep guide
23 topics on how sleep tracking works and where its limits are. In the app and on the web.
History and export
All your nights in one place. Export the data or share it as a text summary.
Privacy
No account and no ads. Sound is processed on the phone in one-minute windows; the recording itself is not stored.
We released Noxuma in June 2026. We wanted a simple sleep app that works right after installing, asks nothing of you and sends your data nowhere. And we wanted our Sleep Phaser lamp to work with iPhone too.
Noxuma records the night with the microphone of a phone placed by the bed. From movement, breathing and sounds it estimates sleep stages and shows them in the morning as a hypnogram. It is an estimate, not a medical measurement — what it picks up and where its limits are is explained in the sleep guide.
Extension
With Sleep Phaser for the whole household
Noxuma works fully with just a phone. A Sleep Phaser lamp adds a light alarm and gives everyone at home their own night — up to 4 lamps from one phone.

Frequently asked questions
How much does Noxuma cost?
Nothing. The app is free, with no subscription, no paid features and no ads.
Do I need an account?
No. Noxuma works without registration and your data stays on your phone.
Does the app record what happens in my bedroom?
Sound is processed on the phone in one-minute windows and the recording itself is not stored. Short clips of possible snoring are kept only if you turn that on.
Is Noxuma a replacement for Sleep as Android?
No. Sleep as Android by the Urbandroid team is our long-standing partner. Noxuma is the path for iPhone and for people who want a simple app with no setup.
Can the app detect a sleep disorder?
No. Noxuma is for personal insight into your sleep. It does not diagnose or treat anything. If sleep troubles you, talk to a doctor.
Where can I find support and the privacy policy?
