Nox: Sleep Canvas & White Noise
Your calm, layered soundscape for deep sleep.
Nox mixes ambient sound, a generative visual canvas, and a smart sleep timer into one quiet space — free to start, no ads, ever.
What's inside
Built for real sleep, not just a timer app
Every detail — from the fade-out curve to the burn-in-safe clock — was designed around one goal: falling asleep, staying asleep.
30 ambient sounds
Six categories, from rain on a tent to deep binaural tones — mix up to 6 at once.
Smart fade-out timer
Volume eases down in the final minutes instead of cutting off mid-dream.
Play through the night
Lock-screen controls and background playback, so the sound keeps you asleep, not just falling asleep.
Nightstand mode
A burn-in-safe bedside clock, dimmed and drifting, for when the phone becomes the nightstand.
Light & dark canvas
A fully designed experience in both themes — calm at night, clear during the day.
Privacy by design
No account, no analytics, no tracking. Everything stays on your device.
A closer look
Designed to disappear into the background
Free to start. Yours to keep.
No trial countdown, no ads anywhere. A single one-time purchase unlocks the rest, whenever you're ready.
