Deep Calm: Sleep & White Noise

Better sleep, already on your phone.

▶ 13 SOUNDS, ZERO DOWNLOADS
Rain · ocean waves · lake shore · white, pink & brown noise · wind · fan · thunder · campfire · heartbeat · night train · theta binaural tones. Some are real recordings baked into the app, the rest are generated live on your phone — nothing to stream, nothing to download, works offline forever.

▶ MIX YOUR PERFECT NIGHT
Play several sounds at once with individual volumes. Save your favourite mixes and start them with one tap.

▶ SLEEP TIMER WITH GENTLE FADE
15 minutes to 1.5 hours — the sound fades out slowly so it never wakes you.

▶ SCREEN OFF, SOUND ON
Keeps playing with the screen locked, with proper media controls.

▶ ONE AD, THEN SILENCE
One advertisement when you open the app — and then nothing, ever. Nothing interrupts your falling asleep. That one ad is what keeps Deep Calm free: it comes from Google AdMob, which uses your device's advertising ID to show and measure it, and you can reset or delete that ID in your Android settings. There is no account and no sign-up — your mixes and volumes are saved on your phone only.

Tonight: rain + distant thunder + 45 minutes. Sleep well.
