Mix rain, a fan, ocean waves and white noise into the sound you sleep or work to. Set each sound's volume, save the mix as a preset, and play it on your iPhone, iPad or in CarPlay. • 24 sounds built in Rain, distant thunder, wind, ocean waves and a bubbling stream. Birds, a pine forest and crickets on a summer night. A train, a sailboat, an airplane cabin and a busy street. A coffee shop, a crackling fireplace, a fan and a dryer in the laundry room. Warm piano, gentle guitar, lo-fi beats and an ambient synth. And the noise family: white, pink, green and deep brown. They all live on your device, so nothing streams. • Build your own mix Turn on any sounds you like and drag each slider until the mix feels right. Save it as a preset, give it artwork, and star your favorites. • Sleep timer Pick how long to listen. Blankie fades out and stops on its own, so nothing runs until morning. • Widgets, Siri and Shortcuts Start a favorite from your Home Screen, ask Siri to play a preset, or build Blankie into your own shortcuts. • Lock Screen, Control Center and AirPods Play, pause and step between presets from the Lock Screen, Control Center or your AirPods. • CarPlay Long drive with a sleeping kid in the back? Your presets and sounds come along, in a simple view made for the car. • Support for iPhone Duo Open it and Now Playing fills one page while your sounds fill the other. Stand it half open on your nightstand and the upright half shows what's playing, with your sounds in reach on the flat half. • Bring your own sounds Bring the fan you can't sleep without, a favorite rain recording, or anything else as MP3, WAV, FLAC and more. Blankie levels each import to match the built-in sounds, so a new sound never blasts over your mix. • Free, private, open source Actually free: no ads, no subscriptions, no accounts, no tracking. Blankie works offline, collects no data, and the code is open source on GitHub.
