About this app

Fall asleep to white noise that never loops, never stops, and never asks for money.

Noisefall generates every sound live on your device — mathematically seamless audio with no loop seams, no gaps, and no downloads. Just tap a sound and drift off.

EVERYTHING IS FREE
• All 12 sounds free — nothing locked, ever
• No ads. Nothing can wake you at 3 AM
• No subscription, no trial, no account
• No tracking or analytics — works fully offline (the only network use is Google Play, and only if you tip)
• Your saved mixes stay yours, always

SOUNDS THAT NEVER LOOP
White noise, pink noise and brown noise for sleep, focus and studying, plus rain sounds, thunderstorm, ocean waves, wind, a babbling stream, box fan, airplane cabin, womb sounds for baby sleep, and a crackling campfire. Because Noisefall synthesizes audio in real time, there are no repeating loops or clicking seams — the rain simply keeps falling all night.

MIX YOUR OWN SOUNDSCAPE
Layer any sounds together and set each volume independently. Rain over brown noise for deep sleep, stream and wind for quiet focus — save any mix as a preset and bring it back with one tap.

SLEEP TIMER WITH GENTLE FADE
Set a sleep timer from 15 minutes to 4 hours. When time is up, your soundscape fades out slowly instead of cutting off — so it never startles you awake.

BUILT FOR ALL NIGHT
Noisefall keeps playing with the screen off using a proper media session, with pause and stop controls right in your notifications. It is designed to sip battery: no network, no background sync, just sound.

PRIVATE BY DESIGN
Noisefall collects no data whatsoever. There is no analytics or tracking, and every feature works offline — everything stays on your device. The only time Noisefall touches the network is Google Play's own billing, and only if you choose to leave a tip.

If Noisefall helps you sleep, there is an optional tip jar in the settings to support future updates. Tipping is never required — every feature is already yours.
