Dimma: Brown Noise for Sleep
White, Pink & Green Sounds
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Dimma is a brown noise app for sleep: brown, white, pink and green noise that plays all night, with a timer that fades. For sleep, tinnitus and focus. No ads.
Sound that is still playing when you wake up.
No ads. No account. No subscription. No hour cap.
13 colours of noise, made live on your phone, with a timer that fades instead of cutting off.
Dimma is a noise machine for the whole night. Pick a colour, tap the light, and it plays until you stop it. If a call or a text interrupts, the sound fades back in by itself and the night line keeps count: on since 23:12, 7 h 48, 0 interruptions.
THE COLOURS
- Brown — deep and warm. Most people sleep here.
- Dark — brown with the top rolled off. Pillow-soft.
- Red — deeper than brown, almost a rumble.
- Infra — the deepest rumble. Best through a speaker.
- Pink — soft and even, a little brighter than brown.
- Velvet — sparse and smooth, softer than white at the same level.
- Balanced — between white and brown. A quiet default.
- Grey — even to the ear across the whole range.
- White — the classic hush for a loud room.
- Green — centred where the ringing lives. Tinnitus listeners keep coming back to it.
- Bright — pink with presence, for daytime focus.
- Blue — bright and airy, for high-pitched ringing.
- Violet — the brightest. Use it low.
Every colour is synthesised on the phone. Nothing loops, nothing downloads, nothing buffers.
FOR THE NIGHT
- All night is the default. Nothing here caps the sound.
- Timers of 15 minutes to 2 hours, or stop at your own sunrise.
- A 9-second to 5-minute fade, so the silence never wakes you.
- Keeps playing after calls and texts, with a small note that it did.
- Lock-screen and Control Centre controls. Next colour from the lock screen.
- The morning page: how long it played, how many interruptions, and one question. Never anything at bedtime.
FOR THE RINGING
- Ringing relief quietens one narrow pitch. Slide it until your own ringing feels covered.
- Set the level just below the ringing. The colours that sit where it lives are Green and Blue.
- Bass, brightness and swell in plain words. No dB, no Hz to learn.
- A speaker is kinder than earbuds; the app says so once.
FOR FOCUS
- Focus, Calm, Breathe and Sleep presets on one pill.
- The swell: a slow rise and fall every 5 to 20 seconds. The light on screen breathes with it.
- A two-hour timer that fades out instead of stopping.
THE PRICE
Every night gives you 15 free minutes with every colour and every control, so you hear the whole thing before you decide. Then it is one payment: $9.99, once, forever. No subscription, no trial, no "per month". Restore on any iPhone.
BUILT QUIET
- No ads, ever. No account. No tracking of what you listen to.
- Nothing to download: the app is small and works offline.
- Dark by design, for a bedroom with the lights off. Dynamic Type, VoiceOver and Reduce Motion respected.
- Loud sound for long periods can harm hearing. Keep the level below the ringing.
Dimma lowers the lights slowly and never surprises you. If it helped, the morning page will ask. If it didn't, tell us: support@trydimma.com
