Pure, synthetic colored noise for focus, sleep, and calm — generated entirely on your device.
Sixteen carefully tuned sounds. One tap to play. Nothing to set up.
White, pink, brown, grey, infra, ultra, focus, lull — plus eight precise frequency bands from 60 Hz to 8 kHz.
15, 30, or 60 minutes with a gentle fade-out so it never wakes you when it stops.
Keeps playing when you lock your screen or switch apps. Click-free transitions between sounds.
Every sound is generated mathematically — no files, no streaming, no internet required.
Noize collects nothing. No accounts. No ads. No tracking. No analytics. No network connection at all — your settings never leave your device.
