Brown noise built for ADHD focus.

Focus Noise is a minimal noise app designed for people who struggle with distractions, overstimulation, and focus — especially those with ADHD.

Most noise apps try to do too much.
We remove everything that breaks focus.

Why Focus Noise?

If you’ve tried focusing with YouTube or Spotify, you already know the problem:
ads, recommendations, sudden interruptions, and constant temptation to switch.

Focus Noise is different.

No ads

No notifications

No playlists

No distractions

Just stable brown noise that helps you stay focused.

Built for Deep, Unbroken Work

Focus Noise is designed to disappear once you press play.

Brown noise optimized for focus and ADHD

Completely stable, seamless looping

Works in the background and on the lock screen

Fully offline — no internet required

No accounts. No setup. No decisions.

Open the app. Press play. Focus.

Free vs Premium

The free version lets you try Focus Noise with a time limit.

Upgrade to Premium for:

Uninterrupted playback

Unlimited focus sessions

Background & lock-screen playback

Offline use

A completely distraction-free experience

You’re not paying for more features.
You’re paying for peace of mind.

Who Is This For?

Adults with ADHD

Students and programmers

Writers, designers, and deep work professionals

Anyone who needs quiet, stable focus without stimulation

Designed With Intention

Focus Noise is not a meditation app.
It’s not a productivity system.
It’s not trying to motivate you.

It’s a quiet tool that stays out of your way — so you can focus.

If Focus Noise helps you stay focused, we’d love to hear from you. ## Rankings - #2,589,657 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_MEDIA_PLAYBACK` - `android.permission.INTERNET` - `android.permission.MODIFY_AUDIO_SETTINGS` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_APP_BADGE` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.RECORD_AUDIO` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.USE_BIOMETRIC` - `android.permission.USE_FINGERPRINT` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `android.permission.WRITE_EXTERNAL_STORAGE` - `com.anddoes.launcher.permission.UPDATE_COUNT` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.htc.launcher.permission.READ_SETTINGS` - `com.htc.launcher.permission.UPDATE_SHORTCUT` - `com.huabeiapi.app.zenstream.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.huawei.android.launcher.permission.CHANGE_BADGE` - `com.huawei.android.launcher.permission.READ_SETTINGS` - `com.huawei.android.launcher.permission.WRITE_SETTINGS` - `com.majeur.launcher.permission.UPDATE_BADGE` - `com.oppo.launcher.permission.READ_SETTINGS` - `com.oppo.launcher.permission.WRITE_SETTINGS` - `com.sec.android.provider.badge.permission.READ` - `com.sec.android.provider.badge.permission.WRITE` - `com.sonyericsson.home.permission.BROADCAST_BADGE` - `com.sonymobile.home.permission.PROVIDER_INSERT_BADGE` - `me.everything.badger.permission.BADGE_COUNT_READ` - `me.everything.badger.permission.BADGE_COUNT_WRITE` ## Similar extensions and apps - [Noiseblinders](https://chrome-stats.com/d/com.ojtechnologiesltd.noiseblinders) — 7 users - [Brown Noise – Focus & Sleep](https://chrome-stats.com/d/se.solidarysolutions.brownnoise) — 28 users - [Hyperfocus App](https://chrome-stats.com/d/com.hyperfocus.app) — 1,856 users - [FocusNoise](https://chrome-stats.com/d/com.focusnoise.app) — 16 users - [ADHD Focus: Brown Noise Timer](https://chrome-stats.com/d/com.bis.focustimer.pomodoro) — 40 users - [Noize: ADHD Focus Sounds](https://chrome-stats.com/d/com.emiazmel.noize) — 2,896 users - [Brown Noise: Sleep & Focus](https://chrome-stats.com/d/com.smarttoolsdev.brownnoise) — 947 users - [Just Noise](https://chrome-stats.com/d/com.justnoise.app) — 24 users - [Pure Sleep & Deep Focus](https://chrome-stats.com/d/com.puresleepdeepfocus) — 28 users - [ADHD Focus Timer – Offline](https://chrome-stats.com/d/com.adhdfocustimeroffline) — 15 users - [ADHDVoice](https://chrome-stats.com/d/com.adhdvoice.app) — 37 users - [Pulse Lab: White Noise & Focus](https://chrome-stats.com/d/com.jdlockhart.ali3npulselab) — 41 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.huabeiapi.app.zenstream)
