Simple White Noise helps you fall asleep, stay asleep and focus, with nearly 100 calming sounds and none of the clutter. No ads, no account, no subscription, and no data collected. REAL RECORDINGS AND LIVE NOISE Field recordings of rain on a tin roof, thunderstorms, ocean surf, waterfalls, crackling fires, dawn birdsong, frogs, crickets, cafés and city streets, each one levelled and looped seamlessly. Alongside them, white, pink, brown, grey and green noise, fans, trains, airplane cabins, a heartbeat, a music box lullaby and singing bowls are generated live on your iPhone, so they never repeat at all. MIX YOUR OWN Layer up to four sounds, set each one's level and save the blend. Start from ready-made mixes like Thunderstorm, Cosy Cabin, Newborn, Night Train and Deep Focus. CREATE YOUR OWN SOUNDS Design a sound from scratch: choose a noise colour, shape it, add movement like waves or gusts, scatter raindrops or crackles over it, and add a hum, drone or chimes. It plays live as you go. Or import your own recording and the app turns it into a seamless loop. MADE FOR SLEEP • A sleep timer that fades out so slowly you won't notice it stop • A gentle fade-in when you start • A volume limit for babies and small speakers • A dim bedside clock that keeps the screen on, with a red-light option and a touch lock so little hands can't stop the sound FOCUS SESSIONS Work in focused blocks with short breaks between them and a longer break after each set. Choose one sound for focusing and another, or silence, for breaks, with a soft chime between phases. EVERYWHERE ON YOUR IPHONE • Lock Screen and Control Center playback controls • A Live Activity and Dynamic Island countdown for your timer • Home Screen and Lock Screen widgets for your favourites • A Control Center control to play or pause • Siri and Shortcuts: "Play rain in White Noise", "Start a sleep timer in White Noise" • AirPlay and Bluetooth speakers BEAUTIFUL ON EVERY SCREEN Designed for Liquid Glass on iOS 26 and later. Layouts adapt to every iPhone and iPad in portrait and landscape. On iPhone Duo, stand it half open and the bedside clock fills the top half while the controls sit on the bottom. PRIVATE BY DESIGN Everything you create stays on your device. The app collects no data at all. Available in 25 languages.
