Your sleep sound machine,
in your pocket

A sleep sound machine plays steady, soothing sound — white noise, rain, a fan, ocean waves — to mask disruptions and help you fall asleep and stay asleep. LumaSleep is a sound machine in app form: the same calming sounds, plus mixing, a sleep timer, and the freedom to take it anywhere.

Yes. A consistent background sound masks the sudden noises — traffic, a snoring partner, a creaky house — that pull you out of light sleep, and gives a racing mind something neutral to settle on. Used nightly it also becomes a cue that tells your brain it's time to rest.

For most adults they're safe and helpful. The only real caution is volume: keep it moderate — around the level of a soft shower — and a few feet from your head. LumaSleep's fade-out timer also lets the sound switch off once you're asleep if you prefer.

Often better. You get far more sounds, the ability to layer and save your own mixes, a sleep timer, and it travels with you to hotels, flights, and a partner's place — without buying extra hardware. The one tip: plug your phone in overnight.

The best one is whichever sound you stop noticing fastest. LumaSleep lets you compare white, pink, brown and green noise plus rain, fan, ocean and fire in a single app, so you can find your match instead of being stuck with a machine's fixed sounds.
