13 calming sounds you can layer into one perfect blend, fade out on a sleep timer, and play all night offline with the screen off.
Turn on steady white noise, drift off in minutes, and stay asleep — with 13 calming sounds you can blend, fade out on a sleep timer, and play all night with the screen off.
Most sound apps ship huge audio files you have to download before bed. Every sound here is generated live on your device, sample by sample, so there is nothing to download, nothing buffering at 2am, and no seam where a loop restarts — it just keeps going, exactly as steady as you left it, even in airplane mode.
WHAT YOU GET
- Fall asleep to 13 sounds: white, pink and brown noise, gentle rain, ocean waves, night forest, oscillating fan, crackling fire, crickets, wind, distant thunder, waterfall and wind chimes
- Build the exact sound your room needs by layering several at once and setting the level of each one independently
- Wake up to silence instead of a phone still playing: the sleep timer (15, 30, 45, 60 or 120 minutes) stops it for you
- Ease into quiet with a gradual fade-out, so nothing snaps off and jolts you awake
- Save your best blends as named soundscapes and bring any of them back with one tap tomorrow night
- Stay in your session with a focus timer at 15, 25, 50 or 90 minutes, running your own mix while you work
PERFECT FOR
- Light sleepers in noisy buildings who need street sounds, footsteps and doors masked
- Parents settling a baby or toddler who only sleeps to steady sound
- Anyone working, studying or reading who needs the room to stop being distracting
- Shift workers and travellers sleeping at odd hours, on planes, or with no signal
WHY NOT JUST PLAY A VIDEO?
Streaming rain drains battery, needs a connection, hits you with mid-roll ads, and gaps every time a track loops. This runs offline as a real-time audio engine with background playback, so one tap gets you an unbroken wall of sound that lasts as long as you want it to.
