Four core noises
White, pink, brown and green — generated live, not looped from a recording. Brown to sleep, pink to focus, and more.
Not just noise —
sound shaped for you.
Noisery generates white, pink, brown and green noise in real time, right on your device. Shape the exact tone you need to fall asleep, focus, or block out the world — then save it and play it again.
Features
Made for the way you wind down.
Real-time sound, shaped to your ears — with none of the clutter.
Shape it to your ears
Depth, softness, space and motion — plus tone focus and width. Move a slider and the sound changes instantly.
Sleep timer & fade-out
Set a time and the sound gently eases away and stops — no worrying about it playing all night.
Save & replay
Keep the noise you create in your library and play it again anytime, in one tap.
Ad-free immersive playback
No ads on the playback or sound-creation screens. The sound keeps going even with the screen off.

Is it really free?
Yes. There's no subscription, one-time purchase, or paid "Pro" tier. You can optionally watch a rewarded ad to unlock extra preset save slots — everything else is free from the start.
What noises are included?
White, pink, brown and green noise, all generated in real time. You can also shape your own tone with depth, softness, space, motion, and tone focus/width.
Does it keep playing in the background?
Yes. Playback continues with the screen off or when you switch apps, so the sound stays with you until your sleep timer ends.
Does the app collect my data?
There's no account and no server of ours — your presets and settings stay on your device. The app uses Google AdMob (ads) and Firebase (analytics & crash reporting); see the Privacy Policy for details.
Do I need an account?
No account needed. Open the app and start listening.
