Still: White Noise & Sleep
A calm white noise app for iPhone and iPad. Tap play and you are listening within a second. Blend white, pink and brown noise with synthesized rain, ocean, wind, fire and fan textures, set each layer's level, save the mixes you like, and let a sleep timer fade everything out.
Still works completely offline. There are no accounts, no ads and no tracking. Core playback is free forever; an optional Still Plus upgrade adds every bedtime story, unlimited saved mixes, and new sounds. Playback continues with the screen locked, with Lock Screen controls and AirPlay.
