HushNest is a free white noise and sleep sounds app for Android and iPhone, made for the whole family. 30 sounds, from white, pink and brown noise to womb, shush, fan, rain and lullabies, each playing over its own painted scene. Mix up to four, set a timer that fades out gently instead of cutting off, or start a one-tap bedtime routine. Works offline and with the screen locked, and needs no account.
