Noisora: Sleep Sounds Offline

Sleep sounds offline turn your phone into a white noise machine the moment you lie down. Noisora plays white noise, rain, ocean waves and other calming nature sounds without Wi-Fi or mobile data: mix your own ambient soundscape, set a sleep timer and turn the screen off. The sounds fade out gently, then the app switches itself off.

ALL SOUNDS OFFLINE
Sleep sounds offline means all 30 sounds are built into the app: nothing to download, no streaming, no account, and it works in airplane mode from the first launch. White, pink, brown, deep brown and green noise are generated live on your phone. Rain, thunder, waves, fire, wind, birds and even the fan or the hair dryer are generated live by Noisora's own sound engine too, so nothing loops and there is never a gap or a click; the purring cat is a real recording, looped with a seamless crossfade. 14 sounds are free forever, and a free sound will never be locked in a later update.

MIX YOUR OWN SOUNDSCAPE
Tap a few sounds to layer them: rain on a tent with distant thunder, ocean waves with a crackling campfire, a fan with soft pink noise. Each layer has its own volume, and a tone control makes the noise brighter or deeper. Mix up to 3 layers for free, or up to 8 with Pro.

SLEEP TIMER THAT FADES
Choose 15, 30, 45 or 60 minutes, 90 minutes, 2, 4 or 8 hours, or Until I stop. When the time is up, the white noise and rain fade out over two minutes, then playback stops completely and nothing is left running in the background to drain your battery. Pro adds any length from 5 minutes to 12 hours, a fade-out from 30 seconds to 30 minutes, Night dim and a separate timer for each layer.

PLAYS ALL NIGHT
Like a bedside sound machine, your soundscape keeps playing with the screen off. Control it from the lock screen, the notification or your headphones, and add 15 minutes with one tap without opening the app. Turn on Play with other apps to keep the rain going under a podcast or an audiobook. Noisora never starts on its own when your phone connects to a car or a Bluetooth speaker.

NO ADS WHILE YOU SLEEP
While the sound is playing, nothing pops up: not an ad, not a paywall, not a message from the app, from the moment you tap Play until the timer ends. The Bedtime screen is pure black with a dim amber countdown, easy on your eyes in a dark room.

READY-MADE SCENES
Start with one of 18 scenes, such as Rainy campfire, Summer storm, Seaside night or Cozy cabin, 7 of them free. Save your favorite mixes (5 for free, unlimited with Pro) and share a mix as a short text code that a friend can paste into the app.

FOR SLEEP, FOCUS AND CALM
Noisora is a relaxation sound machine for every quiet moment: unwind after a stressful day, relax before bed, mask background noise from traffic, neighbours or a snoring partner, focus while you study or work, add a calm background to meditation or yoga, or settle a little one with soft pink noise or a heartbeat. For babies, keep the phone away from the crib and the volume low.

PRIVATE BY DESIGN
Noisora does not use the microphone and does not track your sleep. Every sound is inside the app, and your mixes and settings stay on your phone.
