SleepSound Mixer
Blend rain over a campfire, tuck brown noise underneath, set a timer that fades everything out as you fall asleep. No connection needed — every sound lives on your phone.
Free to download · Pro subscription unlocks the full library
Rain, thunder, ocean, campfire, train, café murmur — plus spectrally accurate white, pink and brown noise.
Stack up to four sounds and balance each one with its own volume slider until the blend is yours.
Pick 15 minutes or three hours. When time is up, the volume eases down slowly — no jarring stop.
Every sound is stored on your device. Airplane mode, basements, long flights — nothing interrupts the night.
Keep your favorite combinations one tap away, or start from presets like Rainy Night and Deep Focus.
Play, pause and check the timer without unlocking. Keeps playing when you unplug your headphones.
