Lullable is an iPhone app of human-narrated bedtime stories for minds that won’t switch off. Listen to slow, softly told stories about history, science, space and nature, with no cliffhangers or plot to keep up with. A sleep timer fades the story to silence, and background playback lets the screen stay dark. Free to download, with an optional Premium subscription ($2.99/month or $19.99/year in the US App Store).
