Sleep Sounds - Noise Mixer

Most sleep sound apps play one track at a time, need internet, or lock the good sounds behind a subscription. Sleep Sounds: Noise Mixer is different: a true multi-layer sound mixer that works 100% offline — blend up to 4 sounds at once, set each layer's volume, and fall asleep to a mix that's exactly yours.

MIX YOUR PERFECT SLEEP SOUND
• Layer up to 4 sounds together — rain over brown noise, wind over ocean waves
• A dedicated volume slider for every layer, so the blend is truly yours
• Save your favorite blends as named mixes and restart them in one tap
• Starter mixes included: Deep Sleep, Rainy Night, Ocean Breeze, Focus

SOUNDS FOR SLEEP, REST & FOCUS
• White noise, pink noise and deep brown noise
• Rain, ocean waves, wind, forest stream, night crickets, thunderstorm
• Cozy campfire crackle and steady fan hum
• Every sound loops seamlessly — no clicks, no gaps

SLEEP TIMER THAT NEVER WAKES YOU
• 15 to 90 minutes, or your own duration
• Volume fades out gently over the last minute — never stops abruptly
• Playback keeps going with the screen locked, with handy media controls

ONE-TAP WIDGET
Add the quick-play widget to your home screen and restart last night's mix with a single tap — no searching, no setup, straight to sleep.

WORKS COMPLETELY OFFLINE
Every sound is built into the app. No downloads, no streaming, no account, no sign-up. Airplane mode? Hotel with bad Wi-Fi? Your sleep sounds always work.

PERFECT FOR
• Falling asleep in noisy apartments, hotels, or while travelling
• Masking tinnitus, traffic, snoring or loud neighbors at night
• Deep-focus work and study sessions with steady background noise
• Winding down with calm nature ambience after a long day

Your data stays on your device — the app collects nothing and your mixes never leave your phone. Build your soundscape tonight and wake up better tomorrow.
